Two rubber blocks are placed on a frictionless flat surface. One
block, with mass 2.5 kg , is launched directly towards
the second, which is stationary and has a mass of
7.0 kg . The two blocks have a perfectly elastic
collision, launching the second block to the right with a speed of
6.0 m/s . What is the velocity of the first block after
the collision, if "to the right" is considered the positive
direction?
