A ball of 0.1 kg makes an elastic head on collision with a ball of unknown mass that is initially at rest. If the 0.1kg ball rebounds at one third of its original speed, what is the mass of the other ball?

A ball of 0.1 kg makes an elastic head on collision with a ball of unknown mass that is initially at rest. If the 0.1kg ball rebounds at one third of its original speed, what is the mass of the other ball?

A ball of 0.1 kg makes an elastic head on collision with a ball of unknown mass that is intitially at rest.If the 0.1 kg ball rebound at one third of its original speed ,what is the mass of the other ball?

A ball of 0.1 makes an elastic collision with a ball of unknown mass that is initially at rest. If the 0.1 kg ball rebounds at one third of its original speed, what is the mas of the other ball ?

A ball of mass 0.1 kg collides elastically with a ball of unknown mass at rest. If 0.1 kg ball rebounds at 1/3 of original speed, find the mass of another ball.

A ball of mass 0.1 kg collides elastically with a ball of unknown mass at rest. If 0.1 kg ball rebounds at 1/3 of original speed, find the mass of another ball.

A moving ball of mass 0.1kg undergoes an elastic head-to-head collision with another body at rest. After collision, the first ball rebounds at one-third of its original speed while second ball starts moving forward . find the mass of the second ball.

A ball A of mass 0.2 strikes another ball B of unknown mass at rest . If the ball A makes an elastic head on collision and then rebounds at one half of its original speed , then calculate the mass of ball B .

A ball of mass 1kg moving with a velocity of 15m // s undergoes a head on elastic collision with another ball of unknown mass at rest, and rebound with a velocity of 10m//s . What is the mass of the other ball?

A ball P of mass 2kg undergoes an elastic collision with another ball Q at rest. After collision, ball P continues to move in its original direction with a speed one-fourth of its original speed. What is the mass of ball Q ?
