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 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 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 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 ball of mass m_(1) , collides elastically and head on with ball of mass m_(2) at rest. Then

A ball of mass m makes head-on elastic collision with a ball of mass urn which is initially at rest. Show that the fractional transfer of energy by the first ball is 4n/(1 + n)^(2) . Deduce the value of n for which the transfer is maximum.

A ball of mass in moving with speed u undergoes a head-on elastic collision with a ball of mass nm initially at rest. The fraction of the incident energy transferred to the second ball is

A ball of 4 kg mass moving with a speed of 3ms^(-1) has a head on elastic collision with a 6 kg mass initially at rest. The speeds of both the bodies after collision are respectively

A ball of mass m makes an elastic collision with another identical ball at rest. Show that if the collision is oblique, the bodies go at right angles to each other after collision.

A ball of mass 5 kg travelling with velocity of 15 cm/s makes a head on collision with another ball of mass 1 kg which is at rest. After the collision, the speed of the lighter ball is

A ball of mass 'm' moving with speed 'u' undergoes a head-on elastic collision with a ball of mass 'nm' initially at rest. Find the fraction of the incident energy transferred to the second ball.
