Homework Help: Finding Max Height

  1. Jun 6, 2009 #1
    Wrongly called for a foul, an angry basketball player throws the ball straight down to the floor if the ball bounces straight up and returns to the floor 2.8 s after first striking it, what was the ball's greatest height above the floor?

    I keep getting the wrong answer I am plugging in (9.8)(1.4)(.5)(1.4)^2(9.81)

    Am I anywhere close?

    Welcome to PF.

    Well ... looks like a few too many factors to have the right answer.

    You know the time and so 1/2 will be time to max height ... you got that part.

    But the distance it will fall in 1.4s is really given a bit more simply by

    y = 1/2*g*t2
