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

    A basketball is thrown horizontally with an initial speed of 4.40 m/s. A straight line is drawn from the release point to the landing point making an angle of 30.0o with the horizontal. WHAT WAS THE RELEASE POINT?

    2. Relevant equations

    tan[tex]\theta[/tex] = y/x
    vfx= vix= 4.40 m/s
    v2fy = v2iy - 2a[tex]\Delta[/tex]y

    a = -g = -9.81

    Hi egadda2! :smile:

    (have a theta: θ :wink:)

    Find the equation for x and t, and the equation for y and t, then put y = xtanθ, and eliminate t. :wink:
