To calculate the energy of the car, we need to determine the type of energy we are interested in. There are several forms of energy, including kinetic energy, potential energy, and various forms of potential and kinetic energy associated with different physical systems.
Since the given information provides the car's velocity, we can calculate its kinetic energy. Kinetic energy is given by the formula:
Kinetic energy = (1/2) * mass * velocity^2
Given: Mass of the car (m) = 3000 kg Velocity of the car (v) = 200 m/s
Substituting these values into the formula, we can calculate the kinetic energy:
Kinetic energy = (1/2) * 3000 kg * (200 m/s)^2
Kinetic energy = 0.5 * 3000 kg * (40000 m^2/s^2)
Kinetic energy = 60000000 Joules (J)
Therefore, when the car has a mass of 3000 kg and moves with a velocity of 200 m/s, its kinetic energy is 60,000,000 Joules (or 60 MJ).
