A cyclist intends on cycle up a 7.8◦ , vertical height is 150 m. Assume the mass of the cycle and cyclist is 75 kgs. a) calculate work done against gravity b) if each complete revolution of the pedal moves the bike 5.1 m along its path, calculate average force exerted on the pedal tangent to circular path. Neglect work done by friction. The pedal turn in circle of diameter of 36 cm
