Assignment:
The pair of blocks, which are connected by a cord, are released from rest when the spring is unstretched. The static and kinetic coefficients of friction are .2 and .1, respectively.
The following things are to be found using the work-energy methods:
1) Maximum Velocity of the blocks
2) Stretch of the spring at the maximum velocity of the blocks
3) Maximum displacement of the blocks during motion
4) Will the blocks rebound from the position of part 3?
