Question

If a train and a car are traveling at the same speed, they have the same amount of kinetic energy.

Answer 1

This argument is false.

Kinetic energy not only depends on the speed but also the mass of the object

Apparently, the mass of car is not equal to the mass of train

Answer 2

This is false because kinetic energy also depends on the mass, and the mass of a train would be different from the mass of a car.
