Question

A body does 1200 joules of work in 2 minutes. calculate its power

Answer 1

Answer :

Given Work done by the body = 1200 J

Given Time = 2 Minutes = 2 × 60 = 120 seconds


Now,


$power \: = \: \frac{work}{time } \\ \\ power \: = \: \frac{1200}{120} \\ \\ power \: = \: \frac{120}{12} \\ \\ power \: = \: 10 \: watts$


Therefore Power = 10 W

Hope it would help you
