A block of mass m1= kg is on a curved track, a distance h= m above the ground as shown here.
When released, it slides down the track and collides elastically with another block of mass
m2= kg, which is sitting at rest.
m2 is larger than m1. This means that m1 will bounce back in the direction from which it came after
the collision. How far back up the track will m1 bounce after the collision?
