A ping-pong ball of mass `m` is floating in air by a jet of water emerging out of a nozzle. If the water strikes the ping-pong ball with a speed `v` and just after collision water falls dead, the mass flow rate of water in the nozzle is equal to :

A ping-pong ball remains dancing at a height in a vertical stream of water.Explain how?

A ball of mass 100g moving at a speed of 12 m s^(-1) strikes another ball of mass 200 g at rest. After the collision both the balls move with a common velocity. Find the common velocity.

Water coming out of a horizontal tube at a speed y strikes normally a vertical wall close to the mouth of the tube and falls down vertically after impact. When the speed of water is increased to 2v,

If a small ping pong ball is placed in a vertical jet of water or air, it will rise to a certain geight above the nozzle and will be spinning there.

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 of mass m moving with a velocity v undergoes an oblique elastic collision with another ball of the same mass m but at rest. After the collision if the two balls move with the same speeds , the angle between their directions of motion will be:
