. Consider the system shown in Figure P10.36 with m1 = kg, m2 = kg, r = m, and the mass of the pulley m = kg. Object m2 is resting on the floor, and object m1 is yi = m above the floor when it is released from rest. The pulley axis is frictionless. The cord is light, does not stretch, and does not slip on the pulley.
(a) Calculate the time interval required for m1 to hit the floor.
(b) How would your answer change if the pulley were massless?

vyi =
