Question

A cyclist overcomes a resistive force or 30 N in order to cycle 30 m. It takes her 6 seconds to cycle this distance. Calculate the power of the cyclist

Answer 1

By the definition of the power, we get:

$$P=\dfrac{W}{t}=\dfrac{Fd}{t}=\dfrac{30\ N\cdot 30\ m}{6\ s}=150\ W.$$

Answer:

$P=150\ W.$
