They actually have the same amount of kinetic energy but the bus I would say is more cuz it weighs more mass, more mass means the more energy it's going to need.

A 4000 kg bus going 40 mph has more kinetic energy than a 2000kg car going 40 mph. tis cuz' KE=1/2*mass*velocity^2 so bus has higher 2x mass of car n 2x KE, even thou their speed is the same.
