Answer 2

Calculation of the Energy of a Car

To calculate the energy of a car, we need to consider its kinetic energy. Kinetic energy is given by the formula:

Kinetic Energy = (1/2) * mass * velocity^2

Given that the car has a mass of 2 tons (or 2000 kg) and is moving at a speed of 54 km/h, we can calculate its energy.

Calculation:

1. Convert the speed from km/h to m/s: - 54 km/h = 54 * (1000/3600) m/s = 15 m/s

2. Calculate the kinetic energy using the formula: - Kinetic Energy = (1/2) * mass * velocity^2 - Kinetic Energy = (1/2) * 2000 kg * (15 m/s)^2

Let's calculate the energy:

Kinetic Energy = (1/2) * 2000 kg * (15 m/s)^2

Using a calculator, we find that the kinetic energy of the car is approximately 225,000 Joules.

Please note that this calculation assumes that the car is moving in a straight line without considering factors such as air resistance or friction.
