A bird is flying with a speed of 18.0 m/s over water when it accidently drops a 2.00 kg fish. If the altitude of the bird is 5.40 m and the friction is disreguarded,what is the speed of the fish when it hits the water?

  • Physics -

    The horizontal component is Vx = 18.0 m/s and the vertical component is
    Vy = sqrt (2 g H)
    H = 5.4 m
    g = 9.8 m/s^2

    The resultant speed is V = sqrt (Vx^2 + Vy^2)
