Physics

Veronica hits a volleyball from a height of 0.4 m and gives it an initial velocity of 5.2 m/s straight up.
a) How high, above the ground, will the volleyball go
b) How long will it take the ball to reach its maximum height?

  1. At the top, v=0
    vf=vi+at
    0=5.2-9.8t
    solve for t.

    Now, at that time
    hf=hi+vi*t-4.9t^2
    hf=.4+5.2t-4.9t^2 put t in, and solve for final height hf
