Question

while working out, a man performed 2525 j of work in 19 seconds. what was his power?
a. 100.5 w
b. 47,975 w
c. 132.9 w
d. 241.5 w

Explanation:

Step1: Recall power formula

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

Step2: Substitute values

Given $W = 2525\ J$ and $t=19\ s$, then $P=\frac{2525}{19}$.

Step3: Calculate result

$P = 132.8947\approx132.9\ W$.

Answer:

C. 132.9 W
