Hello I need help on questions 4,5,6. Work would be appreciate if possible thank you so much!!

6. [-/2 Points] SERPSE10 10.5.0P.017. 0/6 Submissions Used ASK YOUR TEACHER Two boxes are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the gure below. (D The masses of the boxes are m1 = 16.0 kg and m2 = 11.5 kg, the mass of the pulley is M = 5.00 kg, and the radius of the pulley is R = 0.300 m. Box m2 is initially on the floor, and box m1 is initially 4.50 m above the floor when it is released from rest. The pulley's axis has negligible friction. The mass of the rope is small enough to be ignored, and the rope does not slip on the pulley, nor does it stretch. (a) How much time (in s) does it take box m1 to hit the floor after being released? Al\"1 = s (b) How would your answer to part (a) change if the mass of the pulley were neglected? (Enter the time, in seconds, it takes box m1 to hit the floor if the mass of the pulley were neglected.) Atz = s 5. [-/3 Points] SERPSE1010.5.0P.016. 0/6 Submissions Used ASK YOUR TEACHER A torque of 35.6 N ~ m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 9.7 rad/s. After 6.10 s the directed force is removed, and the wheel comes to rest 60.2 5 later. (a) What is the wheel's moment of inertia (in kg - m2)? kgvm2 (b) What is the magnitude of the torque caused by friction (in N ' rn)? N-m (c) From the time the directed force is initially applied, how many revolutions does the wheel 90 through? revolutions u,,,...,i,n. _ i ASK YOUR TEACHER A 155-kg merrygo-round in the shape of a uniform, solid, horizontal disk of radius 1.50 m is set in motion by wrapping a rope about the rim of the disk and pulling on the rope. What constant force would have to be exerted on the rope to bring the merry-go-round from rest to an angular speed of 0900 rev/s in 2.00 5? (State the magnitude of the force.) :1 N Need Help? __ 4.
