Rotational Kinematics with Constant Angular Acceleration: a Machinist Turns the Power

question 49

Multiple Choice

Rotational kinematics with constant angular acceleration: A machinist turns the power on to a grinding wheel, which is at rest at time t = 0.00 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of Rotational kinematics with constant angular acceleration: A machinist turns the power on to a grinding wheel, which is at rest at time t = 0.00 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of   The wheel is run at that angular velocity for 37 s and then power is shut off. The wheel decelerates uniformly at   until the wheel stops. In this situation, the time interval of angular deceleration (slowing down)  is closest to: A)  17 s B)  15 s C)  19 s D)  21 s E)  23 s The wheel is run at that angular velocity for 37 s and then power is shut off.
