# Math Help - Physics proof?

1. ## Physics proof?

My professor asked for us to complete this proof but I am completely stumped. Can anyone please help? Here is all the info he gave us:

x= V_0x(t)+1/2 a_x(t)^2 ---> x=V_0x(t)
y= V_0y(t) + 1/2 a_y(t)^2 ---> y= V_0y(t)

Show: y= f(x) = Ax^2 + Bx + C i.e.
y=f(x) is a parabola and identify A,B,C

I think the parametric equations you're probably meant to be using are:

$\displaystyle x = V_{0x} t$ .... (1)

$\displaystyle y = V_{0y} t + \frac{1}{2} a_{y} t^2$ .... (2)

In which case, from (1): $\displaystyle t = \frac{x}{V_{0x}}$ .... (3)

Substitute (3) into (2) etc.
