A bicycle can put out 4,400 J of work. How much work input is needed for the bicycle to reach 70% efficiency?
Question
Solution 1
To determine the work input needed for the bicycle to reach 70% efficiency, we can use the formula:
Efficiency = (Work output / Work input) * 100
Given that the bicycle can put out 4,400 J of work and the desired efficiency is 70%, we can rearrange the formula to solve for the work input:
