Explanation:
Kinetic energy is the energy acquired due to the motion of an object.
Mathematically, kinetic energy = [tex]\frac{1}{2}mv^{2}[/tex]
where m = mass
v = velocity
Therefore, kinetic energy depends on the mass and square of velocity. Hence, more is the mass of an object more will be its velocity.
Thus, we can conclude that out of the given options, train will have more mass as compared to other objects, therefore, train will have highest kinetic energy.
