Which car has the most kinetic energy? A car of mass 1500 kg with speed 5 m/s or A car of mass 1300 kg with speed 3 m/s or a car of mass 1200 kg with speed 2 m/s or a car mass 1400 kg with speed 4 m/s

The formula to find the kinetic energy of an object is:

KE = 1/2 MV^2

So if we plug in the information

1/2 x 1500 x 5^2

1/2 x 1500 x 25

750 x 25

Car 1 has a KE of 18750

If needed you can find the other three on your own. It'd be good practice.

The answer is car 1.
