Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheelaccelerates uniformly for 10 s and reaches the operating angular velocity of 38 rad/s. the wheel is run at that angular velocity for 30 s and then power is shut off. the wheelslows down uniformly at 2.1 rad/s2until the wheel stops. in this situation, the angularacceleration of the wheel between t = 0 s and t = 10 s is closest to:
a) 6.1 rad/s2
b) 6.8 rad/s2
c) 3.8 rad/s2
d) 4.6 rad/s2
e) 5.3 rad/s2
