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
