A machinist turns the power on to a grinding wheel, at rest, at time t = 0 s.

A machinist turns the power on to a grinding wheel, at rest, at time t = 0 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 58 rad/s. The wheel is run at that angular velocity for 21 s and then power is shut off. The wheel slows down uniformly at 2.4 rad/s2 until the wheel stops. In this situation, the total number of revolutions made by the wheel is closest to:
A)

350
B)

190
C)

240
D)

310
E)

510
