A bucket of water of mass 20 kg is pulled at constant velocity up to a platform 32 meters above the ground. This takes 8 minutes, during which time 6 kg of water drips out at a steady rate through a hole in the bottom. Find the work needed to raise the bucket to the platform. Assume g

W=-1881.6J

Explanation:

we have that the change in the mass is

by solving the differential equation and applying the initial conditions we have

by solving for c and d

d=60

c=0.75

The work needed is

W = m(t) gh

by integrating we have

hope this helps!!

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
