Question

a bag of books took 3 minutes to move you did 12900 j if work how much power was required to move the bad

Answer 1

Power = Work / time

= 12900 J / (3*60)s

≈ 71.667 Watts

Answer 2

71.67 Watts

Step-by-step explanation:

We know that power is the amount of work that is done per unit of time.

The Power formula is

`P=(W)/(t)`

W= work (Jules)

t= time (seconds)

The unit of power is watts

`[P]= (J)/(s)= Watts`

Before applying the formula, we must pass the minutes to seconds so that it is expressed in the correct units.

`3 min.(60s)/(1min)= 180s`

`P=(12900J)/(180s)`

`P= 71.67 Watts`
