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

Answer 1

Given: Mass m = 5.00 Kg;    Height h = 12 m;    Time t = 15 s

Required: Power P = ?

Formula: P = Fd/t  = mgh/t

               P = (5.0 Kg)(9.8 m/s²)(12 m)/15 s

               P = 39.2 Kg.m²/s²  or
 
               P = 39.2 J
