A 1.4-kg wheel in the shape of a cylindrical hoop of radius 0.20 m acquires a rotational rate of 1800 rev/min from rest over a 6.0-s interval at constant angular acceleration. (a) Determine the angular acceleration in (rad/s^2) of the wheel. (b) What is the linear speed (in m/s) and radial acceleration (inm/s2) of a point on the edge of the wheel when it is rotating at 1800 rev/min? (c) What is the rotational kinetic energy (in Joules) of the wheel when it is rotating at 1800 rev/min?
