Hi there!
Recall the following relationships:

W = Work (J)
U = Potential Energy (J)
m = mass (kg)
g = acceleration due to gravity (9.8 m/s²)
h = height (m)
t = time (s)
Begin by calculating the work:

Now, divide by the time to solve for power:

**W is the unit for power (Watts). Be careful not to get the two confused.
