A bicycle and its rider have a total mass of 83.0 kg. Each of its wheels can be modeled as a thin hoop with mass 1.32 kg and diameter of 70.0 cm. When the brakes are applied, two brake pads squeeze the rims of each wheel. Assume that the four brake pads exert normal forces on the wheels that are equal and constant in magnitude. The coefficient of kinetic friction between a brake pad and a wheel is 0.900. The...
