I know how to do this question but just I cannot understand about the question asking 4kg ball. The question is " A 2 kg ball moving at 7m/s strikes a 1 kg ball at rest.The 2kg ball continues to move in the same direction at 3m/s.

a) Find the velocity of the 4kg ball.

b) How much the kinetic energy lost.

c) Find the coefficient of restitution.

I know how to do b) but a) and c) completely I don't know.Can someone show me the steps/guidelines to start with.And from the guidelines I will do myself I know.Thanx
