SUMMARY

The discussion focuses on deriving the time of flight (T) for a projectile launched from an initial height of y=0 to a different level y=h. The formula established is T=1/2To(1+sqrt(1-h/H)), where To represents the time of flight when h=0 and H is the maximum height reached by the projectile. Participants emphasize the importance of understanding basic 2D motion equations and manipulating algebraic expressions to connect the time of flight for different launch and landing heights.

PREREQUISITES

Homework Statement


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.


Homework Equations

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.

Start by finding a statement for To, that is, the time of flight for a projectile that lands at the same level as it is launched.

Then find a statement for time of flight of a projectile that lands at a different level, h.

Then play around with those two statements until they fit together in the way that is asked.

Don't ask me why. The purpose must be to force you to play with the algebra. IT's a useful skill. Think of it as a puzzle.
