A cyclist intends to cycle up a 9.50 degree hill whose vertical height is 115 m. The pedals turn in a circle of diameter 39.0 cm. (Assume the mass of bicycle plus person is 75.0 kg.)
If each complete revolution of the pedals moves the bike 5.40 m along its path, calculate the average force that must be exerted on the pedals tangent to their circular path. Neglect work done by friction and other losses.
F=________N
