Veronica hits a volleyball from a height of 0.4 m and gives it an initial velocity of 5.2 m/s straight up.

Question

a) How high, above the ground, will the volleyball go
b) How long will it take the ball to reach its maximum height?

Answer 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
