A machinist 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
The wheel is run at that angular velocity for 40 s and then power is shut off.The wheel slows down uniformly at
Until the wheel stops.For how long a time after the power is shut off does it take the wheel to stop?
An old LP record that is originally rotating at 33.3 rad/s is given a uniform angular acceleration of 2.15 rad/s2.Through what angle has the record turned when its angular speed reaches 72.0 rad/s?
A wheel rotates through an angle of 13.8 rad as it slows down uniformly from 22.0 rad/s to 13.5 rad/s.What is the magnitude of the angular acceleration of the wheel?
A pulley has an initial angular speed of 12.5 rad/s and a constant angular acceleration of 3.41 rad/s2.Through what angle does the pulley turn in 5.26 s?
