    1. The problem statement, all variables and given/known data

    You are kicking a ball in the air that is sitting on the ground. You are told the initial velocity and the distance to a wall of a known height. To find out if the ball goes over the wall, you need to


    A) determine if the ball is going up or down when it reaches the walls position

    B)determine how fast the ball is going when it reaches the walls position

    C)determine the height of the ball when it reaches the walls position

    D)make sure the ball is at EXACTLY the height of the wall when it reaches the walls position

    E)both a and b

    2. Relevant equations
    change x=vot + 1/2at^2


    3. The attempt at a solution

    I am not sure if the answer is C or E...I keep going back and forth... my reasoning is confusing me. Does anyone know? Thanks. Explanation is appreciated
