Question
A uniform 2.15- kg spinning disk with a radius of 0.333 m is brought to rest by a brake-pad pressed against the side 0.210 m
A uniform 2.15- kg spinning disk with a radius of 0.333 m is brought to rest by a brake-pad pressed against the side 0.210 m from the rotation axis. The wheel is brought to rest from an angular velocity of 20.1 rad/s in a time of 25.7 s. What frictional force was applied by the brake pad?
