Two identical vehicles are moving with same velocity `v` towards an intersection as shown in figure. If the collision is completely inelastic, then

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) When a ball hits a wall (stationary) it returns back with same velocity, if collision is elastic. B) A ball hits a bus moving towards it. If the collision is perfect inelastic, they move together. C) Inelastic collision arises due to loss in K.E during collision

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.

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.

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.

A ball of mass m moving with velocity V , makes a head on elastic collision with a ball of the same moving with velocity 2 V towards it. Taking direction of V as positive velocities of the two balls after collision are.
