A brake system is tested by rotating a tire and measuring the number of rotations required for the brake system to bring the tire to a stop. (Figure 2) The tire's radius is R = 50.0 cm and the brake system's radius is r= 17.7 cm. A moment of
M = 12.7 N-m is applied to the tire for 5 rotations before the brake system is applied. The brake system is composed of two pads that are pushed out against the drum with a force that increases as the tire rotates and is described by
F = (10.00) N. If the coefficient of kinetic friction between the brake pads and the outer ring of the brake system is = 0.550, how many rotations, 7, will the tire go through before coming to a stop?
