The potential energy stored in the boulder is 13720 J.
What is potential energy?
This is the energy of a body due to its position in the gravitational field.
To calculate the potential energy stored in the boulder, we use the formula below.
Formula:
- P.E = mgh................ Equation 1
Where:
- P.E = Potential energy stored in the boulder
- m = mass of the boulder
- h = height of the cliff
- g = acceleration due to gravity
From the question,
Given:
- m = 56 kg
- g = 9.8 m/s²
- h = 45 meters.
Substitute these given values into equation 1
- P.E = 56×45×9.8
- P.E = 13720 J.
Hence, The potential energy stored in the boulder is 13720 J.
