Answer:

Cat with 6 kg sitting on a 30 meter hill has greater potential energy.

Step-by-step explanation:

gravitational potential energy (J) = mass (kg) × gravitational field × height (m)

Note:

gravitational field in Earth is 10 N/kg = fixed unit

Given:

1st Cat: 4 kg

2nd Cat: 6 kg

Both of their height is 30 meters.

Solve for g.p.e:

1st cat = mgh = 4 × 10 × 30 = 1200 Joules

2nd cat = mgh = 6 × 10 × 30 = 1800 Joules
