Which object has the greatest kinetic energy? a a truck with a mass of 3,500 kg moving at 30 m/s b a person with a mass of 73 kg running 6 m/s c a fast pitched baseball with a mass of .5 kg moving at 46.9 m/s d a locomotive engine with a mass of 205,000 kg moving 5 m/s
The object with the greatest kinetic energy is d) a locomotive engine with a mass of 205,000 kg moving at 5 m/s. This is because kinetic energy is calculated using the formula KE = 0.5 * mass * velocity^2, so the higher the mass and velocity, the greater the kinetic energy.
