Question

An object of mass 20 kg is raised vertically through a distance of 8 m above ground level. If g = 10 m/s2, what is the gravitational potential energy of this object at this position?

Answer 1

1600 joules

Step-by-step explanation:

Potential Energy = m * g * h

= 20 kg * 10 m/s^2 * 8 m = 1600 J
