A body of mass `4 kg` moving with velocity `12 m//s` collides with another body of mass `6 kg` at rest. If two bodies stick together after collision , then the loss of kinetic energy of system is

A body of mass 5 kg moving with a velocity 10 m/s collides with another body of the mass 20 kg at, rest and comes to rest. The velocity of the second body due to collision is

A body of mass 5 kg moving with a velocity of 6 m s^(-1) collide with another body of mass 2 kg which is at rest. Afterwards they move in the same direction as before. If the velocity of the body of mass 2 kg 10 ms^(-1) , find the velocity and kinetic energy to the body of mass 5 kg.

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 0.5 kg moving with a velocity of 6 m//s collides with another body of mass 2 kg moving at 2 m//s and travelling in opposite direction. If the two bodies travel together after the collision, find the velocity of combined mass and the loss of kinetic energy.

A body of mass 1 kg moving with velocity 10 m//s collides with another body moving in opposite direction of mass 3 kg and velocity 3 m//s . After collision both the bodies move together. What is their common velocity?

A body of mass 20 gm is moving with a certain velocity. It collides with another body of mass 80 gm at rest. The collision is perfectly inelastic. The ratio of the kinetic energies before and after collision of the system is

A body of mass 3 kg moving with a velocity (2hati+3hatj+3hatk) m/s collides with another body of mass 4 kg moving with a velocity (3hati+2hatj-3hatk) m/s. The two bodies stick together after collision. The velocity of the composite body is
