    How Far Does Dave Johnson's Center of Mass Move Up During the High Jump?

    Oh it is gravity then! So you work out time (t=0.612) and then find displacement (s=3.67)

    Dave Johnson, the bronze medallist at the 1992 Olympic decathalon in Barcelona, leaves the ground at the high jump with vertical velocity component 6 m/s. How far does his center of mass move up as he makes the jump?
