2....A ball with a mass of 2 kg move to the right with a speed of 2 m/s. It hits a ball of mass 0.50 kg which is at rest. After collision the second ball moves to the right with a speed of 1 m/s. What happens to the first ball?...Suppose that the 2 balls stick together moves as one after collision, what is their final velocity?

2. Momentum is conserved.

**drwls**, Friday, February 18, 2011 at 9:03am1. Impulse = force x time

= momentum change

Apply the formula

2. Total momentum remains the same.

In the second case,

M1* (2 m/s) = (M1 + M2)*Vfinal

Vfinal = (2/2.5)* 2 m/s = __

Try doing the first case yourself. Make sure + is right and - is left for velocity.
