A circular disc of radius 50.0 cmand mass 9.5 kgstarts spinning… A circular disc of radius? ?50.0 cmand mass? ?9.5 kgstarts spinning from rest about its central axis, and undergoes an angular acceleration under a constant torque of 3.0 N m.Take? ??????as the moment of inertia of the circular disc.a)Calculate the angular acceleration of the wheel. b)What is the work done by the torque in the first 8 seconds of angular acceleration?c)The rotational axis is now shifted (parallel to the central axis) a distance of 40.0 cm from the central axis. Using the parallel axis theorem, determine the new moment of inertia.SciencePhysics PHYSICS 120
