Ball A of mass m strickes a stationary ball B of mass M and undergoes an elastic collision. After collision bill A has a speed one third of its initial speed. The ratio of M/m is

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 ?

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 particle of mass m_1 makes a head on elastic collision with another stationary body of mass m_2 , If m_1 rebounds with half of its original speed then (m_1 /m_2) is

A body of mass m_(1) moving at a constant speed undergoes an elastic head on collision with a body of mass m_(2) initially at rest. The ratio of the kinetic energy of mass m_(1) after the collision to that before the collision is -

A body of mass m_(1) moving at a constant speed undergoes an elastic head on collision with a body of mass m_(2) initially at rest. The ratio of the kinetic energy of mass m_(1) after the collision to that before the collision is -

A particle of mass m_1 , makes a head on elastic collision with another stationary body of mass m_2 If m_1 , rebounds with half of its original speed then (m_1/m_2) is

A particle of mass m_1 , makes a head on elastic collision with another stationary body of mass m_2 If m_1 , rebounds with half of its original speed then (m_1/m_2) is

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?
