A gray kangaroo can bound across a flat stretch of ground with each jump carrying it 9.3 m from the takeoff point. If the kangaroo leaves the ground at a 17.6 degree angle, what is its takeoff speed?

  • physics -

    The distance covered in each jump is

    9.3 m = (Vo^2/g)*sin(2*17.6)

    g = 9.8 m/s^2

    9.3 = [Vo^2/9.8]*0.5764

    Solve for Vo

    12.57
