A car has a kinetic energy of 432,000j when traveling at 32 meters a second, what's the cars mass?

Answer:843.75kg

Explanation:

kinetic energy (ke) = 432000j

Velocity (v) = 32m/s

Mass (m) = ?

Ke = (mxv^2) / 2

432000 = (mx32^2) / 2

432000 = (mx32x32) / 2

Cross multiplying we get

432000x2 = (mx1024)

864000=1024m

Divide both sides by 1024

864000/1024=1024m/1024

843.75=m

m=843.75kg
