Derive algebraic expressions for the range and total time-of-flight of a projectile launched with initial speed v, from a height h, and at an angle Q, above the horizontal. We were given the final equations but I am unsure of how to derive them.

2. Relevant equations

range=vt-.5gt^2, where g is the acceleration due to gravity and t is the time in seconds.

time= (vsinQ+((vsinQ)^2+2gh)^.5)/g

3. The attempt at a solution

Considering the ball, after it has been launched:

Fx=0

Vox=vcosQ

Fy=mg

Voy=vsinQ

?
