What is "if a 1000 kg car is traveling at 3 meters per second?

Assuming the car is on a flat surface and not experiencing any external forces such as air resistance or friction, we can calculate the kinetic energy of the car using the formula:

Kinetic energy = 0.5 * mass * velocity^2

Plugging in the given values:

Kinetic energy = 0.5 * 1000 kg * (3 m/s)^2 Kinetic energy = 0.5 * 1000 kg * 9 m^2/s^2 Kinetic energy = 4500 Joules

Therefore, the kinetic energy of a 1000 kg car traveling at 3 meters per second is 4500 Joules.
