(c) The figure below shows the apparatus you used in Lab 2: a disc of radius R = 0.114 m, a shaft of radius r = 0.0126 m and a mass m = 20 g. A string is wrapped around the shaft and tied to the mass m at the other end. The mass m = 20 g is dropped from rest for a height of 0.714 m from the floor to rotate the shaft and the disc. It takes 22.3 s for the mass to drop on to the floor for the height of 0.714 m. The mass of the shaft is considered negligible. (i) Determine the angular acceleration of the disc when the mass m is dropping.
(ii) Calculate the centripetal acceleration at point A of the disc just before the mass hits the floor.
