A 1533 kg car is traveling down the road at 90.6 km/h. While traveling at this rate of speed, what is the kinetic energy of this vehicle in kilojoules?

Chemistry 
DrBob222,
KE = (1/2)*m*v^2
KE in joules = (1/2)*1533 kg x v^2
Convert 90.6 km/hr into m/s and substitute into the above formula, Solve for KE. I get 25.17 m/s for the conversion but you should confirm that. .
