By rubbing the bottom of a 0.3 kg block with the adhesive and pushing it tightly to the turntable 0.4 metres from its base, a turntable is used to measure a deliberately poor adhesive. The turntable begins at t=0 and accelerates uniformly with an angular acceleration of a= 4.5 rad/s2. Determine what to do if the adhesive breaks precisely 2 seconds after the turntable begins rotating: (a) The turntable's angular displacement at the moment of failure. (b) At the moment of failure, the amount of revolutions the turntable had produced. (c) The overall shear force that the adhesive will withstand in the event of a breakdown.
