Question 1182592: What is the potential energy of 3.00 kg object at the bottom of a well 10.0 m deep as measured from ground level. Explain the sign of the answer
(b) How much work is required to lift a 3.00 kg object from the bottom of a well 10.00 m deep

P E = m *g * h
height on ground is 0 m
height is negative below the ground
P E = 3 * 10m/s^2 * (-10)
PE =-300 Joules
Change in P E = work done
