An object which has a mass of 70 kg is sitting on a cliff 10 m high. calculate the object's potential energy. given g = 10m/s2 question 16 options: a) 7,000 joules b) 3,500 joules c) 70 joules d) 35 joules e) 700 joules

Answer is a.)

Given: Mass m = 70 Kg   Height  h = 10 m;        g = 10 m/s²

Required. Gravitational Potential Energy or P.E

Formula: P.E = mgh

                     = (70 Kg)(10 m/s²)( 10 m)

              P.E = 7,000 Kg.m²/s² or

              P.E = 7,000 J
