(a) How long does it take for the grinding wheel to stop?

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

**Henry**, Wednesday, May 4, 2011 at 9:59pma. V=95rad/min * 6.28rad/rev * (1/60)min/s = 9.94rad/s.

Vf = Vo - at = 0,

9.94 - 2.4t = 0,

-2.4t = - 9.94,

t = 4.14s.
