An object with a mass of m=4.7 kg is attached to the free end of a light string wrapped around a reel of radius R=0.270 m and a mass of M=3.00 kg. The reel is a solid disc, free to rotate in a vertical plane about the horizontal axis passing through its center as shown in figure below. The suspended object is released from rest 7.00 m above the floor. Determine tension in the string. Determine the magnitude of the acceleration of the object. Determine the speed with which the object hits the floor.
