A professional cyclist rides a bicycle that is 92 percent efficient. For every 100 joules of energy he exerts as input work on the pedals, how many joules of output work are used to move the bicycle?

Since Efficiency = 92% = 0.92
Efficiency = (Work Output) / (Work Input) 0.92 = Wo / 100 Wo = 0.92 * 100 Wo = 92 J. Therefore 92J is used to move the bicycle.

When a professional cyclist exerts 100 joules of energy on a bicycle that is 92% efficient, 92 joules of output work are used to move the bicycle. This calculation is based on the efficiency formula, which relates input and output work. Therefore, with 100 joules of input, the effective work done to move the bicycle is 92 joules.
