Consider the system shown in the figure below with?m1?=?28.0?kg,?m2?=?10.2?kg,?R?=?0.290?m,?and the mass of the pulley?M?= 5.00 kg.?Object?m2?is resting on the floor, and object?m1?is?4.40?mabove 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.
Calculate the time interval required for?m1?to hit the floor.?
?t1?= ? ? ? s
(b) How would your answer change if the pulley were massless?
