A physics student throws a softball straight up into the air. The ball was in the air for a total of 6.16 s before it was caught at its original position.
(a) What was the initial velocity of the ball?
(b) How high did it rise?

    time to top = 3.08 s
    v = Vi - gt
    v is 0 at top
    so
    Vi = 9.8*3.08

    h = Vi t - 4.9 t^2 where t = 3.08

    46.578224
