Answer:
Explanation:
The kinetic energy will convert to heat energy (provided the car has friction brakes and not regenerative brakes as might be found on an electric or hybrid) Also<u> assuming level road</u>.

Well, electric and magnetic are actually the same in nature (as basic force in the Universe). The four, in decreasing order of strength, are:
Strong nuclear, Weak nuclear, Electric/Magnetic (in roughly the same range) and Gravitational (much weaker than Electric/Magnetic -- a magnet less than 1 kg beats Earth which is quite a lot of gigatons, roughly)
