Acyclist intends to cycle up a 7.70o hill whose vertical height is 126m. assuming the mass of bicycle plus person is 75.0kg, calculate how much work must be done against gravity. if each complete revolution of the pedals moves the bike 5.12m 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. the pedals turn in a circle of diameter 38.8cm.
