The driver of a car slams on her brakes to avoid colliding with a deer crossing the highway. What happens to the car's kinetic energy as it comes to rest?

  • physics -

    The brakes get hot and the tires and road surface get hot

  • physics -

    Kinetic energy = 1/2 * mv^(2)
    Then when v decreases, the kinetic energy decreases as well
