A grinding wheel is spinning at a rate of 20 revolutions per
second. When the power to the grinder is turned off, the grinding
wheel slows with constant angular acceleration and takes 80.0 s to
come to a rest. A) What was the angular acceleration of the
grinding wheel as it came to rest? Should the angular acceleration
be negative or postive and why?

A machinist turns on the power on to a grinding wheel at time t = 0s. The wheel accelerates uniformly from rest for 10s and reaches the operating angular speed of 58 rad/s. The wheel is run at that angular velocity for 30s, and then power is shut off. The wheel slows down uniformly at 1.4 rad/s^2 until the wheel stops. What is the total number of revolutions made by the wheel in this situation ? A machinist turns on...

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 40 rad/s. The wheel is run at that angular velocity for 34 s and then power is shut off. The wheel slows down uniformly at 2.8 rad/s2 until the wheel stops. In this situation, the time interval of deceleration is closest to:

Constants Part A A high-speed flywheel in a motor is spinning at 500 rpm (revolutions per minute) when a power failure suddenly occurs. The flywheel has mass 39.0 kg and diameter 79.0 cm. The power is off for 25.0 s and during this time the flywheel slows due to friction in its axle bearings. During the time the power is off, the flywheel makes 150 complete revolutions. At what rate is the flywheel spinning when the power comes back on?...
