Question
An object with a mass of m = 5.4 kg is attached to the free end of a light string wrapped around a reel of radius R = 0.230 m and mass of M = 3.00 kg. The reel is a solid disk, free to rotate in a vertical plane
about the horizontal axis passing through its center as shown in the figure below. The suspended object is released from rest 6.60 m above the floor.
M
(a) Determine the tension in the string.
N
(b) Determine the magnitude of the acceleration of the object.
m/s?
(c) Determine the speed with which the object hits the floor.
m/s
(d) Verify your answer to part (c) by using the isolated system (energy) model. (Do this on paper. Your instructor may ask you to turn in this work.)
