Question

9.
5. 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.
10
Ans. 375 J​

Answer 1

Explanation:

Solution:

Gravitational potential energy = U = mgh

m = 2.5 kg

g = 10 N

h = 15 m

U = 2.5 \times 10 \times 15

U = 375 J
