Homework Statement
The graph I have posted is the result of using a motion sensor above a bouncing ball.
I am asked to write a clear interpretation of the meaning of each parameter in the equation Y=At^2+Bt+C.
Homework Equations
Y=Ax^2+Bt+C
y=y0+v0t+1/2at^2

I think relating the above two equations that B is the initial velocity and C is the initial position. "A" however is confusing me.
Also if C is indeed the initial position I'm not quite sure I understand why it is negative.
