A ping-pong ball strikes a wall with a velocity of 10 ms^(-1) . If the collision is perfectly elastic, find the velocity if ball after impact

A ping-pong ball strikes a wall with a velocity of 10 ms^(-1) . If the collision is perfectly elastic, find the velocity if ball after impact

A ball moving on a horizontal frictionless plane hits an identical ball at rest with a velocity of 0.5m//s . If the collision is elastic, calculate the speed imparted to the target ball, if the speed of projectile after the collision is 30cm//s .

A ball of mass 10 kg is moving with a velocity of 10 m / s . It strikes another ball of mass 5 kg which is moving in the same direction with a velocity of 4 m / s . If the collision is elastic, their velocities after the collision will be, respectively

A ball moving with a velocity v strikes a wall moving toward the wall with a velocity u. An elastic impact occurs. Determine the velocity of the ball after the impact. What is the cause of the change in the kinetic energy of the ball ? Consider the mass of the wall to be infinitely great.

If a ball strickes with a velocity u_(1) at the wall which itself is approaching it with a velocity u_(2) then find the velocity of the ball after collision with the wall.

If a ball strickes with a velocity u_(1) at the wall which itself is approaching it with a velocity u_(2) then find the velocity of the ball after collision with the wall.

A wall moving with velocity 2 cms^(-1) towards the ball and ball is moving towards the wall with a velocity 10 cms^(-1) . It hits the wall normally and makes elastic collision with wall. The velocity of ball after collision with wall in cms^(-1) .
