a bus and a car have the same momentum . which one them has greater kinetic energy

Asked by enigma | 3rd Nov, 2009, 07:52: PM

Expert Answer:

K.E. = P2 / 2m

From the above expression, it is clear that K.E. energy is inversly proportional to mass ; momentum remaining constant.

Since, bus and car have the same momentum , the car has greater K.E.
