This is a pretty simple physics problem, but I do not know how to go about it.
How do I:
Show that the time required for a projectile to reach its highest point is equal to the time for it to return to its original height?

Physics 
drwls,
The maximum height is where V = 0.
The acceleration rate is g, in either direction.
The initial speed is the same as the final speed (because of conservation of energy.)
The time it takes to decelerate from initial speed V to 0 is V/g.
The time it takes to accelerate from 0 to V is also V/g
This works whether the projectile goes straight up or not. V represents the vertical velocity component.
