A ball of mass 1 kg moving with a velocity of "0.4 ms"^(-1) collides with another stationary ball. After the collision, the first ball moves with a velocity of 0.3ms^(1) in a direction making an angle of 90^(@) with its initial direction. The momentum of the second ball after the collision will be (in kg ms^(-1) )

A ball of mass 2kg moving with speed 5m/s collides directly with another ball of mass 3kg moving in the same direction with speed 4m/s. The coefficient of restitution is 2/3. Find the velocities of both ball after the collision.
