Answer:
The mass of the cat is 4.534 kg
Explanation:
Given
gravitational potential energy
= 88.9 J
Height h = 2.0 m
To find: mass of the cat
We know that the gravitational potential energy is given by
= mgh, where
m = mass of body
g = acceleration due to gravity = 9.8 m/
h = height above ground
Hence , mass m = 
= 
= 4.534 kg
Hence the mass of the cat is 4.534 kg
