Question

Two objects are connected to a cord, and the cord is hung over a pulley connected to the ceiling, as shown in the figure below. m2 The masses of the objects are m1-18.0 kg and m2-10.0 kg, the mass of the pulley is M-5.00 kg, and the radius of the pulley is R = 0.100 m. Object m2 įs initially on the floor, and object m1 is initially 4.30 m above the floor when it is released from rest. The pulleys axis has negligible friction. The mass of the cord is small enough to be ignored, and the cord does not slip on the pulley, nor does it stretch. (a) How much time (in s) does it take object m1 to hit the floor after being released? b) How would your answer to part a change if the mass of the pulley were neglected? Enter the time n seconds it takes o pulley were neglected.) e t m. to ht e O ·f the as of e At
