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?
