A cannon is fired from a cliff 190 m high downward at an angle of 21° with respect to the horizontal. If the muzzle velocity is 34 m/s, what is its speed (in m/s) when it hits the ground?

  • Physics -

    The kinetic energy will increase by
    M g H.
    Vfinal^2/2 - Vo^2/2 = g H
    (M cancelled out)

    Solve for Vfinal
