Question

A cat jumps from 2.5-meter-tall bookshelf to a 1.3-meter-tall countertop. If the cat

Answer 1

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
