Question

A girl lifts a 100 N load to a height of 2.0 m in 0.5 sec. What power does the girl produce?

Answer 1

Answer:400 watts

Step-by-step explanation:

you have to solve for work using work=FD

then solve for power using P equals W over tea

Answer 2

Answer: The power produced by the girl is 400 watts.

Explanation-

According to the question, load (w) = 100N

Height, h = 2.0m

Time taken, t = 0.5 sec

Mathematically, Power = Work done/ Time taken

Work( W) = Force × Distance

= Load × Height

= 100 × 2.0 = 200 Joules

Putting the value of work and time in the formula of power, we get-

Power = 200Joule /0.5 sec

= 400 watts
