The two masses shown in Fig. 4-50 are each
initially 1.8 m above the ground, and the massless frictionless pulley is 4.8 m
above the ground. What maximum height does the lighter object reach after the
system is released? [Hint: First determine the acceleration of the lighter mass
and then its velocity at the moment the heavier one hits the ground. This is
its “launch” speed. Assume the mass doesn’t hit the pulley. Ignore the mass of
the cord.]
