A wheel (M = 6.51 kg, R = radius 0.524 m) in the shape of a disk is rotating at fo = 81.6 rpm when a tool is
Find:
a) τ, the magnitude of the torque exerted by the tool on the wheel
b) ΔL, the magnitude of the change in the angular momentum of the wheel during the time the wheel was slowing down
c) at, the magnitude of the tangential acceleration of the wheel as it slowed down
d) ar, the magnitude of the radial acceleration of a point on the edge of the wheel at the end of the 4.42 seconds
