Question

Find the gravitational potential energy of 2.5 kg mass kept at a height of 15 m above the ground. The force of gravity on mass 1 kg is 10 N. ​

Answer 1

Answer:

18.75 joules

Explanation:

Mass = 2.5 kg

Height = 15 m

g = 10 N (The force of gravity remains same on all objects)

Potential Energy = 1/2mgh

                             = 1/2 * 2.5 * 15

                             = 18.75 joules
