A turntable rotates at 33 rev/min and takes 15 seconds to come to rest.
a) What is the angular acceleration?
b) How many rotations does the turntable make before coming to rest?
33 rev/min = 33* 2Pi/60 (rad/s) = 11Pi/10 (rad/s)
w = w0 - alpha *t ...
The solution calculates the angular acceleration for a turntable
