Embibe Experts Solutions for Exercise 4: Assignment

A ball is thrown from the ground with velocity $u$ at an angle $\theta$ with horizontal. The horizontal range of the ball on the ground is $R.$ If the coefficient of restitution is $e,$ then the horizontal range after the collision is

A stationary particle explodes into two particles of masses $x$ and $y,$ which move in opposite directions with velocity $v_1$ and $v_2.$ The ratio of their kinetic energies $\left(E_1:E_2\right)$ is

Two balls of equal mass undergo head on collision while each was moving with speed $6 \mathrm{m} {\mathrm{s}}^{-1}.$ If the coefficient of restitution is $\frac{1}{3},$ the speed of each ball after impact will be

A ball of mass $M$ moving with speed $V$ collides perfectly inelastically with another ball of mass $m$ at rest. The magnitude of impulse imparted to the first ball is

A ball of mass $m$ is dropped from height $h$ on a horizontal floor which collides with it with speed $U.$ If coefficient of restitution in floor is $\theta ,$ then impulse imparted to ball by the floor on its second rebounce is

A ball is dropped from height $h$ on a horizontal floor. If it loses $60\%$ of its energy on hitting the floor then height upto which it will rise after first rebounce is

A ball dropped from height $h$ on a horizontal floor goes up to the height $\frac{3h}{4}$ after hitting the floor. Fraction of energy of ball lost in the impact is

A ball is dropped on a horizontal surface from height $h.$ If it rebounds upto height $\frac{h}{2}$ after first collision then coefficient of restitution between ball and surface is
