Question

Jill pulls on a rope to lift a 12 kg pail out of a well, while the clumsy jack watches. For a 10.0 meter segment of the lift, she lifts the bucket straight up at constant speed. How much power is required to complete this task in 5 seconds?

Answer 1

1. Power = <b>work</b> / time

2. work = force x distance

3. f = mg

-----------------------------------------

plug in values starting from equation 3 and go up to equation 1. g stands for gravity constant, and m stands for mass. f stands for force.

Answer 2

12 N
