Question

while working out, a man performed 2525 j of work in 19 seconds. what was his power?
a 132.9 w
b 241.5 w
c 47,975 w
d 190.5 w

Explanation:

Step1: Recall the power formula

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

Step2: Substitute the given values

Given \( W = 2525\ J \) and \( t=19\ s \). Then \( P=\frac{2525}{19} \).

Step3: Calculate the value

\( \frac{2525}{19}=132.8947\approx132.9\ W \)

Answer:

A. 132.9 W
