Answer is: potential energy is 1960 J.

m (medicine ball) = 40 kg.

h = 5 m.

g = 9,8 m/s².

Ep = m·g·h.

Ep = 40 kg · 9,8 m/s² · 5 m.

Ep = 1960 N·m = 1960 J.

Joule is equal to the energy transferred to an object when a force of one newton acts on that object (in this case medicine ball) in the direction of its motion through a distance of one metre.
