A particle is launched with velocity v from ground level at an angle to the horizontal. It is possible to show that its height above ground is given by the function
sy(t) = v*t*sin (r) - (1/2) g*t^2
where g is the downward acceleration due to gravity. For what value of t is sy maximized?
You should derive an expression in terms of v; and g.
t =

So from what I can tell I need to derive the function in a certain way (way to go sherlock), something that I can do easily with a simple function with just one variable.
I am wondering how would I go about solving this and how do you "derive an expression in terms of v; and g" ?
