Problem

Two carts collide on a smooth horizontal track. Cart A has mass

2\,\text{kg}

and moves at

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

to the right; cart B has mass

3\,\text{kg}

and is initially at rest. The coefficient of restitution for the collision is

0.6

. (i) Calculate the velocity of cart A immediately after impact. (ii) Calculate the velocity of cart B immediately after impact.
