Jordan tosses a ball upwards with an initial velocity of 14.0 m/s. What is the displacement in meters of the ball during the first 2.5 seconds after she threw it? (don't include units in the answer, use 10.0 m/s2 for g and use the upward direction as positive)

    vf = vi + at
    ? = 14 + 2.5(-9.8)
    vf = .571
    vf^2 = vi^2 + 2ad
    (.571)^2 = (14)^2 + 2(-10)(d)
    9.78
