All of the following objects are moving at the same speed. Which one has the greatest kinetic energy?

Aa bicycle

Ba motorcycle

Ca car

Da semi tractor-trailer truck

Verified Answer :

Hagrid

Having the same speed, a semi
tractor – trailer truck has the greatest kinetic energy among the four. This is
because kinetic energy is directly proportional with half of the square of the
velocity times the mass of the object in motion. As the mass is increased, with
the same speed, the kinetic energy increases.
