A cyclist intends to cycle up a 7.50 degree hill whose vertical height is 135m. The pedals turn in a circle of diameter 37cm. If each complete revolution of the pedals moves the bike 5.60m along its path. use energy conservation:
how much energy did the bicycle gain after one revolution of the pedals?
if this energy all comes from the work the cyclist does, what would be the distance the feet of the cyclist travel? according to the definition of work, what would be the average force then? about 1 and a half cups. |
