A railway truck of mass `16000 kg` moving with a velocity of `5ms^(-1)` strikes another truck of mass `4000 kg` at rest. If they move together after impact, their common velocity is

A sphere of mass 2kg strikes another sphere of mass 3kg at rest with a velocity of 5ms^(-1) .If they move together after collision, then common velocity is

A spere of mass 20 kg moving with a velocity 40 ms^(-1) collides with another sphere of mass 15 kg which is at rest . After collision they move with the same velocity . Find the velocity .

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 ball of mass 100g moving at a speed of 12 m s^(-1) strikes another ball of mass 200 g at rest. After the collision both the balls move with a common velocity. Find the common velocity.

A sphere of mass 0.3 kg moving with a velocity of 4 m/s collides with another sphere of mass 0.5 kg which is at rest. Assuming the collision to be elastic, their velocities after the impact are
