Question

A machine runs for 50 seconds with a steady power output of 100 watts. How many joules of work does the

machine produce in those 90 seconds?

Answer 1

The answer to your question is when time = 50 s, work = 5000 J

when time = 90 s, work = 9000 J

Step-by-step explanation:

Data

time = 50 s or 90 s

Power = 100 watts

Power is defined as the rate of work done per unit of time.

Power = Work / time

-Solve for Work

Work = Power x time

-Substitution

Work = 100 x 50

-Result

Work = 5000

2.-When time = 90 s

Work = 100 x 90

-Result

Work = 9000 watts
