Question

while working out, a man performed 500 j of work in 8 seconds. what was his power?

a. 38.5 w
b. 62.5 w
c. 500 w
d. 4000 w

Explanation:

Step1: Recall power formula

Power $P=\frac{W}{t}$, where $W$ is work and $t$ is time.

Step2: Substitute values

Given $W = 500\ J$ and $t=8\ s$, so $P=\frac{500}{8}$.

Step3: Calculate result

$P = 62.5\ W$.

Answer:

B. 62.5 W
