Obtain frictional force was applied by the brake pad

Reference no: EM13514008

A uniform 2.15- kg spinning disk with a radius of 0.233 m is brought to rest by a brake-pad pressed against the side 0.149 m from the rotation axis. The wheel is brought to rest from an angular velocity of 17.3 rad/s in a time of 20.5 s. What frictional force was applied by the brake pad?
