a 17 of model plane is flying at a horizontal speed of 14 m/s

the plane goes into a dive and levels off 21 m closer to the earth what was the ammount of potentiomal energy lost in the dive

  • PHYSICS -

    a 17 kg

  • PHYSICS -

    P.E. loss = M g H
    = 17 kg * 9.8 m/s^2 * 21 m = 3500 J

    The speed does not matter
