Projectile Motion - Finding theta

[tatterspwn]

Homework Statement

Iv'e been given a graphed parabola with each x interval at 0.1000s. From this I need to find R, Tt, H, V₀, a and θ.

Homework Equations

Tt= 2 (Vsinθ/g)
R= (V²sin2θ)/g
H=(Vsinθ)²)/2g

The Attempt at a Solution

From observing the graph I know:
d_x and d_y at every 1/10 of a second.
Tt= 2.000s
R= 14.50cm
H= 10.00cm

From here I have no idea how to find V₀ or θ. I'm not sure what one I have to find first in order to get the other. Any help is appreciated.

it sounds like you were given the distance that the object traveled and its max height through this graph

by looking at the x-direction and y-direction separately, you should be able to determine the initial velocity in both the x and y directions
