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 doesnt hit the pulley. Ignore the mass of

the cord.]
