Stephanie serves a volleyball from a height of 0.76 m and gives it an initial velocity of +7.2m/s straight up.How high will the volleyball go? The acceleration of gravity is 9.81 m/s2.
Answer in units of m.

2) How long will it take the ball to reach its maximum height? Answer in units of s.

  • physics -

    vi^2=mgh where h is the height above .76m, so add that to h.

    how long? when you find the h(before you add)
    h=vi*t-4.9t^2 solve for t.
