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
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
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.
