Question

A green car is traveling at a rate of 30 m/s. A brown car is traveling at a rate of 45 m/s. The cars have equal masses. Compare the kinetic energy of the two cars.

Answer 1

Answer: The car traveling at a rate of 45 m/s has more kinetic energy than the car traveling at a rate of 30 m/s because kinetic energy increases as velocity increases. The masses of the two cars are equal, so the only factor affecting the kinetic energy is their velocities.
