while working out, a man performed 2525 j of work in 19 seconds. what was his power?\na. 100.5 w\nb. 47,975 w\nc. 132.9 w\nd. 241.5 w
Answer
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
