An object with a mass of m = 4.65 kg is attached to the free end of a light string wrapped around a reel of radius R = 0.225 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 5.20 m above the floor. (a) Determine the tension in the string (in N). N (b) Determine the magnitude of the acceleration of the object (in m/s2). m/s2 (c) Determine the speed with which the object hits the floor (in m/s). m/s
