The prompt:
"A 20-kilowatt motor operates an elevator weighing 10,000 N. What is the maximum speed at which the motor can raise the elevator?"
How can i solve for speed?
I know that power = work / time, and work = force * distance, but I cannot solve for work because I only know a force without a distance, and I cannot solve for power because I don't know work NOR time... What am i missing here?
**EDIT**
Wow I just realized that P = w/t = f*d/t = f * d/t = F*V
With that being said, I can use P = F*V, or in my case, 20000 = 10000*X... Right?
