The change in Potential energy of the cat is 176.4 J.
Potential Energy:
This is the energy due to the position of a body. The S.I unit is Joules (J)
The formula for change in potential energy.
Formula:
- ΔP.E = mg(H-h).............. Equation 1
Where:
- ΔP.E = Change in potential energy
- m = mass of the cat
- g = acceleration due to gravity
- H = First height
- h = second height.
From the question,
Given:
- m = 15 kg
- H = 2.5 m
- h = 1.3 m
- g = 9.8 m/s²
Substitute these values into equation 1
- ΔP.E = 15×9.8(2.5-1.3)
- ΔP.E = 15×9.8×1.2
- ΔP.E = 176.4 J.
Hence, The change in Potential energy of the cat is 176.4 J
