Question

How long would it take a 500 w electric motor to do 150,000 j of work

Answer 1

We know the power is equal to the work done over time (that is, P=W/t)

Plugging in the given values, 500=150000/t
=> t=300 s

Answer 2

Step-by-step explanation:

300 second = 5 minutes

details

500 watts = 500 joules per second

Time = (1.50 x 10^5 joules)/(5 x 10^2 joules per second) = .3 x 10^3 seconds =300 second
