The lightweight wheel on a road bike has a moment of inertia of 0.097 kg⋅ m 2 . a mechanic, checking the alignment of the wheel, gives it a quick spin; it completes 5 rotations in 2 s . to bring the wheel to rest, the mechanic gently applies the disk brakes, which squeeze pads against a metal disk connected to the wheel. the pads touch the disk 7.1 cm from the axle, and the wheel slows down and stops in 1.4 s . what is the magnitude of the friction force on the disk?
