Question

A 2,000 kg car is parked at the top of a 30 m high hill. what is its potential energy?

Answer 1

Answer: The potential energy would be 600kiloJoule

Explanation: The Potential energy of a body is a function of it's wieght mg and height h. That is

Potential energy,

P.E = mass* acceleration due to gravity* height

Acceleration due to gravity is a constant 10m/s²

Potential energy = 2000*10*30 =600000Joule which is also 600kilojoule

Answer 2

The PE for this question will be 588,000 because we take the mass (2,000 kg), multiply it by 9.8 which is Gravitational Acceleration and then multiply that by the height (30 meters)
