A motor has an output of 1000 watts. When the motor is working a full capacity, how much time will it require to lift a 50 Newton weight 100 meters?

Explanation:

Use the power equation here:

P = W/t where W is work and is defined as

W = F* displacement

so the Power equation can be written as

P = (F*displacement)/t and we have everything we need except time, our unknown:

1000 = (50*100)/t and

(1000*100)/50 = t so

t = 2.0 × 10³ seconds

I dont get it.
