What is the increase in potential energy when a 20-kg block of ice is lifted a vertical distance of 2 m?

1 Answer

392 J

Explanation:

"Potential energy= mass*gravitational acceleration*height"

Mass is measured in kilograms (kg), gravity in m/s^2 and height in meters (m).

E_p=m*g*h

It is measured in Joules (J)

20*9.8*2=392 J
