Question

Suppose a woman raises a 65 N object in 2m in 4 seconds.

Calculate the work is done and her power.


Science

Answer 1

`\huge\boxed{\sf P.E = 130\ Joules}`

`\huge\boxed{\sf P = 32.5\ Watts}`

Step-by-step explanation:

Given Data:

Weight = W = 65 N

Height = h = 2 m

Time = t = 4 secs

Required:

Power = P = ?

Work Done in the form of Potential Energy = P.E. = ?

Formula:

P.E. = Wh

P = P.E. / t

Solution:

P.E. = (65)(2)

P.E = 130 Joules

P = P.E. / t

P = 130 / 4

P = 32.5 Watts

`\rule[225]{225}{2}`

Hope this helped!
