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?

Part II: Through how many radians has the wheel turned during the interval found in (a)?

rad

If possible just a brief explanation how you got the answer? Thanks.
