At highest point vertical component of velocity becomes zero but horizontal components remains. Net velocity is along horizontal Also acceleration is vertically downwards throughout the journey Hence the correct option is c.

Since velocity is changing, KE and momentum is not constant. Now since acceleration is vertically downwards, vertical component of velocity is changing. Since there is no acceleration is horizontal direction, horizontal components is constant Hence the correct option is d. Speed of particle is constant in uniform circular motion Velocity vector is tangent to the path at any point on the path.

Acceleration vector is directly inwards towards center So velocity and acceleration vector are perpendicular to each other in Uniform circular motion Hence the answer is a and b. Time taken to reach the ground depends on the velocity in vertical direction Since both the bodies are projected horizontally. There are no vertical components of velocity involved. So they will reach the ground in same time. Now time taken is same so body with more horizontal velocity will travel more on the ground.

Hence the answer is a and b. At the highest point of projectile, vertical components of velocity becomes zero. So there are only horizontal components so, net velocity is horizontal at this point. Now acceleration is vertically downwards throughout the motion.

So acceleration and velocity vector are perpendicular to each other at highest point. It is evident; we must have horizontal velocity of projectile equal to horizontal velocity of the airplane.

## JEE Level Projectile motion problems

Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile , and its path is called its trajectory. The motion of falling objects, as covered in Problem-Solving Basics for One-Dimensional Kinematics, is a simple one-dimensional type of projectile motion in which there is no horizontal movement. The most important fact to remember here is that motions along perpendicular axes are independent and thus can be analyzed separately. This fact was discussed in Kinematics in Two Dimensions: An Introduction , where vertical and horizontal motions were seen to be independent. The key to analyzing two-dimensional projectile motion is to break it into two motions, one along the horizontal axis and the other along the vertical. This choice of axes is the most sensible, because acceleration due to gravity is vertical—thus, there will be no acceleration along the horizontal axis when air resistance is negligible.

Projectile Motion Problems On this page I put together a collection of projectile motion problems to help you understand projectile motion better. The required equations and background reading to solve these problems is given on the projectile motion page. I also provide hints and numerical answers for these problems. Refer to the figure below along with sign convention shown , for problems For problems and 8, ignore air resistance in your calculations.

The velocity time graph describes the motion of an object that is projected vertically. Study the graph and answer the following questions: After how many.

## JEE Level Projectile motion problems

Projectile motion is the motion of an object thrown or projected into the air, subject only to acceleration as a result of gravity. The applications of projectile motion in physics and engineering are numerous. Such objects are called projectiles and their path is called a trajectory. The motion of falling objects as discussed in Motion Along a Straight Line is a simple one-dimensional type of projectile motion in which there is no horizontal movement. In this section, we consider two-dimensional projectile motion, and our treatment neglects the effects of air resistance.

Which of the following statements are true of scalars and vectors? List all that are TRUE. TRUE - Vectors are defined as quantities which are fully described by both their magnitude and direction. By definition, a vector has a direction associated with it. If it didn't, then it would NOT be a vector.

At highest point vertical component of velocity becomes zero but horizontal components remains.

We now study the motion of objects that are moving upwards or downwards while experiencing a force due to gravity. We call this projectile motion. When we talk about a projectile we mean a body or particle that is project or launched and then moves under the influence of only gravity. We know from Newton's Law of Universal Gravitation that an object in the Earth's gravitational field experiences a force pulling it towards the centre of the Earth. If this is the only force acting on the object then the object will accelerate towards the centre of the Earth. A person standing on the Earth's surface will interpret this acceleration as objects always falling downwards. We also ignore any effects that air resistance drag might have.

A projectile is an object upon which the only force acting is gravity. There are a variety of examples of projectiles. An object dropped from rest is a projectile provided that the influence of air resistance is negligible. An object that is thrown vertically upward is also a projectile provided that the influence of air resistance is negligible. And an object which is thrown upward at an angle to the horizontal is also a projectile provided that the influence of air resistance is negligible.

Even though there are a number of questions to answer, the best approach is to work through them one at a time. First, as with rectilinear motion in Grade

Складывалось впечатление, что он отключился сам по. Сьюзан знала, что такое могло произойти только по одной причине - если бы в Следопыте завелся вирус. Вирусы были самой большой неприятностью, с которой сталкивались в своей работе программисты.

- Как бы там ни было, ты поможешь мне с моей рукописью. - Рукописью. - Да. Я решила ее издать.

Темнота коридора перетекла в просторное цементное помещение, пропитанное запахом пота и алкоголя, и Беккеру открылась абсолютно сюрреалистическая картина: в глубокой пещере двигались, слившись в сплошную массу, сотни человеческих тел. Они наклонялись и распрямлялись, прижав руки к бокам, а их головы при этом раскачивались, как безжизненные шары, едва прикрепленные к негнущимся спинам. Какие-то безумцы ныряли со сцены в это людское море, и его волны швыряли их вперед и назад, как волейбольные мячи на пляже. Откуда-то сверху падали пульсирующие стробоскопические вспышки света, придававшие всему этому сходство со старым немым кино.

ГЛАВА 43 В свои сорок пять Чед Бринкерхофф отличался тем, что носил тщательно отутюженные костюмы, был всегда аккуратно причесан и прекрасно информирован. На легком летнем костюме, как и на загорелой коже, не было ни морщинки. Его густые волосы имели натуральный песочный оттенок, а глаза отливали яркой голубизной, которая только усиливалась слегка тонированными контактными линзами. Оглядывая свой роскошно меблированный кабинет, он думал о том, что достиг потолка в структуре АНБ. Его кабинет находился на девятом этаже - в так называемом Коридоре красного дерева.

- Тогда мы с вами придем к соглашению. - Буду держать вас в курсе, - произнес голос, и вслед за этим в трубке раздались короткие гудки. ГЛАВА 14 Беккер впился глазами в труп. Даже через несколько часов после смерти лицо азиата отливало чуть розоватым загаром.

На подиуме все замолчали, не отрывая глаз от экрана. Джабба нажал на клавиатуре несколько клавиш, и картинка на экране изменилась. В левом верхнем углу появилось послание Танкадо: ТЕПЕРЬ ВАС МОЖЕТ СПАСТИ ТОЛЬКО ПРАВДА Правая часть экрана отображала внутренний вид мини-автобуса и сгрудившихся вокруг камеры Беккера и двух агентов. В центре возник нечеткий из-за атмосферных помех кадр, который затем превратился в черно-белую картинку парка.

Он лжет, - фыркнула Мидж.  - Я два года проверяю отчеты шифровалки.

- Он взял у Джаббы мобильный телефон и нажал несколько кнопок.  - Мидж, - сказал.  - Говорит Лиланд Фонтейн. Слушайте меня внимательно… ГЛАВА 112 - Надеюсь, вы знаете, что делаете, директор, - холодно сказал Джабба.

Ты это уже. - Вот. Она нахмурилась.

Чтобы он получил второй ключ. - Что еще за второй ключ.
