Calculate the potential energy of a 25kg boulders at the ledge of a 150m high
Crank

Answer:

36750J

Explanation:

Potential energy, which is the energy of a body at rest or in a position is calculated as follows;

P.E = m × g × h

Where;

m = mass (kg)

g = acceleration due to gravity = 9.8m/s²

h = height of the boulder (m)

According to the provided information;

m = 25kg, h = 150m

Using P.E = m.g.h

P.E = 25 × 9.8 × 150

P.E = 36750 Joules
