Problem

0.25\,\text{kg}

ball A moving to the right with a speed of

6.0\,\text{m\,s}^{-1}

strikes ball B of mass

0.35\,\text{kg}

which is at rest on the same straight line. After the impact, ball A continues to move to the right but with a reduced speed of

2.0\,\text{m\,s}^{-1}

. Calculate the coefficient of restitution between the balls.
