Homework Statement



Projectile is launched off cliff at 45 degrees. The coordinates from which the thing is launched are (4.5, 4.8). I had to do this via computer simulation (interactive physics) with different Vxo and Vyo used

Given:
Xo 4.5
Yo 4.8

I additionally recorded the Hmax, Xf and the Vo can be found because the components are given

We compare the computer readout (reading a graph) and maunally check if the computer solves for g correctly

Homework Equations



R=(Vo)2/g times sin2theta

If their was no cliff and launched from ground, R is |Xf-Xo|

For another problem, when a projectile was launched from the ground and impacts the ground, I put in all the variables and solved for g and recorded the percent error of that solved variable (g) from 9.81

The Attempt at a Solution



Try to use the range equation. I can't remember if my professor said I had to use this. If not, then I can varify g using the max height when the Vfy is 0. Just wondering if it is possible.
