Question
A car (1,500 kg) is sitting at the top of a 20 m tall on ramp. What is the cars potential energy?
Solution
To calculate the potential energy of the car, we can use the formula for gravitational potential energy:
PE = mgh
where: PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above the ground.
Given: m = 1500 kg (mass of the car), g = 9.8 m/s² (acceleration due to gravity on Earth), and h = 20 m (height of the ramp).
Substituting these values into the formula, we get:
PE = 1500 kg * 9.8 m/s² * 20 m = 294,000 Joules
So, the potential energy of the car at the top of the ramp is 294,000 Joules.
