A `6 kg` mass collides with a body at rest. After the collision, they travel together with a velocity one third the velocity of `6 kg` mass. The mass of the second body is

A 6kg mass collides with a body at rest. After the collision, they travel together with a velocity one third the velocity of 6 kg mass. The mass of the secon body is

A 5kg mass collides with a body at rest. After the collision, they travel together with a velocity one third the velocity of 5kg mass. The mass of the second body is

A body of mass 5 kg makes an elastic collision with another body at rest and continues to move in the original direction after the collision with a velocity equal to 1//10^(th) of its original velocity. The mass of the second body is

A body of mass 2 kg moving with uniform velocity of 40 ms^(-1) collides with another body at rest . If two bodies move together with a velocity of 20 ms^(-1) . Find the mass of the other body .

A body of mass m, moving with velocity mu collides elasticity with another body at rest having mass M. If the body of mass M moves with velocity V, then the velocity of the body of mass m after the impact is

A body of mass 5 kg makes an elastic collision with another body at rest and continues to move in the original direction after collision with velocity equal to (1)/(10) th of its original velocity . Then the mass of the second body is

A body of mass 2 kg makes an elastic head - on collision another body at rest and continues to move in the original direction with one fourth of its original speed . The mass of the second body which collides with the first body is
