Question

You raise a bucket of water from the bottom of a well that is 12 m deep. The mass of the bucket and the water is 5.00 kg, and it takes 15 s to raise the bucket to the top of the well. How much power is required?

Pe= 60.00
Work= Force*direction

Answer 1

P = F * d/t = M*g * d/t = 5*9.8 * 12/15 = 39.2 J/s = 39.2 Watts.

Answer 3

Power = Energy/Time
We have time, but we need to find the energy.
to do this use the equation for potential energy: PE = (mass)(gravity)(height)
plug in the numbers: PE = (5kg)(9.8m/s^2)(12m) = 588J
now that we have the energy, just divide it by the time! P = 588J/12s = 39.2W
hope this helps :)
