A. 132.9 W
B. 241.5 W
C. 47.975 W
D. 100.5 W

Answer :

Answer:

Power of the man is 132.9 W.

Explanation:

Given that,

Work performed by the man is 2525 J

Time for which the work is performed is 19 second

To find :

Power of the man

Solve :

Let P is the power of the man. The total work done divided by time taken is called the power of an object. Its formula is given by :

[tex]P=\dfrac{W}{t}[/tex]

[tex]P=\dfrac{2525\ J}{19\ s}[/tex]

[tex]P=132.89\ W[/tex]

or

[tex]P=132.9\ W[/tex]

Therefore, the power of the man is 132.9 W.

A: 132.9w because 2525\19 is how much energy transferred per second which is also known as the power
