Homework Statement
Find out the launch velocity from the launcher (the absolute starting point aka x=0)
Angle (degrees) Height(cm) Average Distance Traveld(cm)
0 99.0 220.73
30 104.3 307.8
45 106.6 380.4
60 108.5 319.2
Homework Equations
We were given a equation on the board, but I think I copied it incorrectly:
Vi=sqrt(gx^2/cos^2theta(xtantheta-y))
The Attempt at a Solution
I get a very wrong solution with said equation, because I know that the velocity should change.
