Find the linear momentum and kinetic energy of a bullet of mass 4.80e-2 kg moving at a speed of 320 m/s.

I found the linear momentum to be 15.36 by doing m*v but I can't figure out the kinetic energy.

  • Physics -

    yes on the momentum
    Ke = (1/2) m v^2

    thanks! I'm studying for a test and this helps me tremendously!
