21. Blocks of mass mi and m2 are connected by a massless string that pulls over the pulley in
the figure. The table is frictionless. The pulley is a frictionless disk, but it does have mass
Me and radius R (Lask=1/2MR?). Consider that m2 is initially hanging at rest H meters
above the ground.
a. Write the general formulas for the translational KE, rotational KE, gravitational PE,
spring PE.
