How do i find this? A shooting star is a meteor that burns up when it reaches Earth's atmosphere. Many of these meteoroids are quite small. Calculate the kinetic energy of a meteoroid of mass 6.0 g moving at a speed of 45 km/s and compare it to the kinetic energy of a 1400-kg car moving at 29 m/s (65 mi/h). (Find kinetic energy of the meteor and of the car)

  • physics -

    KE= 1/2 m v^2 where m is in kg, and v in m/s.

    Compute that for both, and compare.

  • physics -

    i got 6.075E12 for the meteor
    and 588,700 for the car, but both answers are still wrong.
