Rotational Kinematics - Turntable

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?

Solution Preview

a)
33 rev/min = 33* 2Pi/60 (rad/s) = 11Pi/10 (rad/s)

w = w0 - alpha *t ...

Solution Summary
