An electric motor rotating a workshop grinding wheel at a rate
of 1.19 ✕ 102 rev/min is switched off. Assume the wheel has a
constant negative angular acceleration of magnitude 2.10
rad/s2.
a How long does it take for the grinding wheel to stop?
s
(b) Through how many radians has the wheel turned during the
interval found in (a)?
