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

solve projectile motion formulas for [tex]\Theta[/tex] and [tex]v_0[/tex]

all measurements are in m, t is seconds

[tex]y_0=.005[/tex]

[tex]x_0=0[/tex]

the averages from my trials were:

[tex]x=8.775 m[/tex]

[tex]t=1.3 s[/tex]

2. Relevant equations

[tex]x=x_0+v_0*cos\Theta*t[/tex]

[tex]y=y_0+v_0*sin\Theta*t+.5a_yt^2[/tex]

3. The attempt at a solution

after plugging in my numbers gives:

for x

[tex]6.75=v_0*cos\Theta[/tex]

which as far as I can see still has two unknowns, where do I go from here?

I'm pretty confused about the y component because I'm not even sure what y is supposed to be. Don't I need a y(max) number first?
