  1. time up equals time down ... so the ball takes (6.36 s / 2) to travel up (or down)

    distance = 1/2 g t^2 = 1/2 * 9.81 m/s^2 * (6.36 s / 2)^2

  2. if yalll didnt understand, here also b/c why not

    vf-vi=at, so find that negative number then divide by two and it will give u |vi|
    make it positive
    vf =0 at the top, so
    0^2=vi^2 + 2a ∆x
    then
    -(vi^2)/(2a){should be 19.6}= ∆x
