0.20\,\text{kg}

glider slides at

5.0\,\text{m/s}

on a frictionless air track and collides elastically with a

0.40\,\text{kg}

glider at rest. The second glider then collides elastically with a

0.60\,\text{kg}

glider that was also at rest. Find the speed of the

0.60\,\text{kg}

glider after all collisions have occurred.
