Homework Statement
Derive equations (5) and (6). Calculate at what angles the time and range are maximized.
(5) t= ((2 * Vo) / g) * sin[tex]\theta[/tex]
(6) Range = x1-xo = ((2 * Vo)/g)(sin[tex]\theta[/tex])(cos[tex]\theta[/tex])= (Vo^2/g)(sin2[tex]\theta[/tex])
sorry about the confusing format. I'm new to latex and new to this forum
Homework Equations
(1) Vox = Vo * cos[tex]\theta[/tex]
(2) Voy = Vo * sin[tex]\theta[/tex]
(3) Range = X - Xo = Vox * t
(4) Y - Yo = Voy * t - (1/2)gt^2
The Attempt at a Solution
I have no clue how to derive an equation. This is my first physics class I've taken ever and it was never taught by my professor on how to derive an equation.
i hope you guys can bear with the tiny amount of knowledge i have. i tried googling instructions and ways on how to derive an equation but i still don't understand the concept. thanks!
