a scared kangaroo clears a fence that is 2.44 meters tall. what is the vertical component of the kangaroos velocity at take off (vfi) ? if the horizontal component of the kangaroos velocity is 4.80m/s at what angle did the kangaroo take off the ground? (hint: at its maximum height the kangaroos vertical velocity is 0)

  • physics -

    Vfi^2 = 2gH
    H = 2.44 m, g = 9.8 m

    Solve for Vfi, the initial vertical component.

    Vfi/4.80 = tanA

    Solve for the angle A.
