Well, in order to find Power we need work to find Joules/second, which equates to a Watt, which is going to be the 'power output' of the motor. P=W/t

Is time really needed to solve this equation? I guess not since we've already figured out that Acceleration is zero. But in order to find work we still need distance...ideas?

Homework Statement An 8.5x102 elevator (including occupants) is pulled up at a constant velocity of 1.00 m/s by an electric motor. Calculate the power output of the electric motor. Homework Equations P=W/t F=ma v=d/t a=v/t The Attempt at a Solution Having trouble...

I was kind of hoping you'd have some ideas ;)

Homework Statement An object(mass=525kg) is 3.0x103 km above the Earth's surface. This object is falling toward the Earth because of the Earth's gravitational force on it. What is the rate of acceleration when it is at this distance? Homework Equations Mass of Earth=5.98x1024 Radius...

Thanks for your help Lunar Lander, the formula definitely helps :smile: but what I'm having the most trouble with(I should have included this in the question) is knowing what is the Force Applied, Resistive force, etc...any ideas? Thanks again.

Homework Statement A 1.20x103 kg car is traveling at a speed of 22.5 m/s when the brakes are applied. If the car comes to a stop in 112m, what is the braking force?(Assume Uniform deceleration) Homework Equations Fnet=Fapp-FR Fnet=ma Fg=mg The Attempt at a Solution...
