A cyclist competes in a one-lap race around a flat, circular course of radius 140 m. Starting from rest and speeding up at a constant rate throughout the race, the cyclist covers the entire course in 60 s. The mass of the bicycle (including the rider) is 76 kg. Find Ff,net, the magnitude of the net force acting on the cyclist at the finish line. What is the magnitude of the net force Fnet acting on the bicycle as it crosses the finish line?
