    Kinetic Energy & Stopping Force of a Car

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    A car of mass 1500 kg is moving with a speed of 50 km/h (13.89 m/s). Determine the kinetic energy T of the car.

    (see options a through d in attached file)

    Now determine the force required to stop the car at a distance of 50 m, if the kinetic energy T is 1.447 x 10E5 N-m. 10E5 means 10 to the 5th power.
    a. 1447 N
    b. 2894 N
    c. 3000 N
    d. 5000 N
