    Inability to calculate kinetic energy if I use SI units

    Homework Statement If a 2000 lb car with a velocity of 88 ft/s has by my calculations a kinetic energy of 240 kJ. But for a 909kg car with a velocity of 26.73 m/s I calculate 324.7 kJ. Same velocity, same mass, different energy calculation. Homework Equations English units: Kinetic...
