Question

A car, a train, a bicycle, and a skateboard are traveling at the same speed. Which object has the greatest kinetic energy?

Answer 1

Answer: Train

Since the train is the largest, it has more momentum. Adding the momentum to the speed, gives it the most kinetic energy. After train would come car, then bicycle, then skateboard.

Hope I helped! :)

Answer 2

the train because it would have the most momentum sliding against the tracks and this would increase the kinetic energy or the heat of the object
