Question

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

Answer 1

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`
