A sphere of mass `m` slides with velocity `v` on as frictionless surface towards a smooth inclined wall as shown in figure. If the collision with the wall is perfectly elastic find a. the impulse imparted by the wall on the sphere `b` the impulse imparted by the floor on the sphere.

As the coefficient is elastic so the sphere will rebound with the same speed after collision. `J_(1)costheta=J_(2)`…….i `-mv+J_(1)sintheta=mv`…………..ii solving eqn i and ii we get `J_(2)=2mv cot theta` `J_(1)=2mv cosec theta`
Two balls each of mass 'm' are moving with same velocity v on a smooth surface as shown in figure. If all collisions between the balls and balls with the wall are perfectly elastic, the possible number of collisions between the balls and wall together is
A ball of mass m strikes a rigid walJ with speed u and rebounds with the same speed. The impulse imparted to the ball by the wall is
A ball of mass m strikes a rigid walJ with speed u and rebounds with the same speed. The impulse imparted to the ball by the wall is
Two sphere A and B are placed between two vertical walls as shown in figure. Draw the free body diagrams of both the spheres
A ball is moving with velocity 2m//s towards a heavy wall moving towards the ball with speed 1m//s as shown in figure. Assuming collision to be elastic, find the velocity of ball immediately after the collision.
