Answer:
the cat with a mass of 6 kg
Step-by-step explanation:
Potential Energy : Weight x Height
PE of cat w/ mass 4 kg :
- PE = 4 x 10 x 30
- PE = 40 x 30
- PE = 1200 J
PE of cat w/ mass 6 kg :
- PE = 6 x 10 x 30
- PE = 60 x 30
- PE = 1800 J
Clearly, the cat with a mass of 6 kg has greater potential energy.
