A sphere of mass 4kg, moving with velocity 5 `ms^(-1)` collide with another sphere of mass 2 kg moving with velocity 2 `ms^(-1)` in the same direction on linear path. After the collision the first sphere is moving in the same direction with velocity 3 `ms^(-1)`. What would be the velocity of the second sphere after collision?

Text Solution

Verified by Experts
