1. The problem statement, all variables and given/known data 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 ?
