Amachinist turns on the power on to a grinding wheel at time t= 0 s. the wheel accelerates uniformly from rest for 10 s and reaches the operating angular speed of 58rad/s. the wheel is run at that angular velocity for 30 s, and then power is shut off. the wheel slows down uniformly at 1.4rad/s^2 until the wheel stops. what is the total number of revolutions made by the wheel in this situation? a) 340 b) 390 c) 430 d) 570 e) 300
