Question: An electric motor rotating a workshop grinding wheel at a rate of 9.10 101 rpm is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 1.50 rad/s2.
Part I: How long does it take for the grinding wheel to stop?
s
Part II: Through how many radians has the wheel turned during the interval found in (a)?
rad
