1. The problem statement, all variables and given/known data A projectile fired from y=0 with initial speed Vo and initial angle (-) lands on a different level, y=h. Show that the time of flight of the projectile is T=1/2To(1+sqrt(1-h/H)) where To is the time of flight for h=0 and H is the maximum hieght of the projectile. 2. Relevant equations basic 2d motion equations 3. The attempt at a solution I need a hint of where to start on this thing. I'm not even sure what its asking me to do.
