Answer:
P.E = 13230 J
Explanation:
Given,
The mass of the rock, m = 45 Kg
The rock is sitting at a height from the ground, h = 30 m
The acceleration due to gravity, g = 9.8 m/s²
The potential energy of the body is given by the formula,
P.E = mgh joules
Substituting the given values in the above equation
P.E = 45 x 9.8 x 30
= 13230 J
Hence, the potential energy of the rock is P.E = 13230 J
