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 body of mass 0.1 kg travelling with a velocity of 5 m/s, collides head-on with another body of mass 0.2 kg travelling in the same direction with a velocity of 1.2 m/s. If the two bodies stick together after collision, their common velocity is

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 truck of mass 2xx10^(4) kg travelling at 0.5ms^(-1) collides with another truck of half its mass moving in the opposite direction with a velocity of 0.4ms^(-1) . If the trucks couple automatically on collision, calculate the common velocity with which they move.

Stationary bomb explodesinto three pieces. One piece of 2kg mass moves with a velocity of 8 ms ^(-1) at right angles to the other piece of mass 1 kg moving. With a velocity of 12 ms^(-1) . If the mass of the third piece is 0.5kg , then its velocity is

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 A of mass m moving with a velocity hits another stationary sphere B of same mass. If the ratio of the velocity of the sphere after collision is (v_(A))/(v_(B)) = (1 - e)/(1 + e) where e is the cofficient of restitution, what is the initial velocity of sphere A with which it strikes?

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

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 stick to each other and move with a common velocity. Find the common velocity.
