An object (with mass m = 5.00 kg) is attached to the free end of a massless string wrapped around a reel of radius R = 0.300 m and mass M = 4.00 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. The suspended object is released from rest 5.00 m above the floor. Calculate the magnitude of the acceleration (in m/s^2) of the object. Round your answer to 2 decimal places. Note: I = (1/2)MR^2 for a solid disk.
