Physics Problem: Projectile Motion  (Abstract Concept Formation)

(Rubin!, right click on SVG picture!)

As shown in the above figure , at time , (Rubin change embedded mml size!) cannon fires a projectile with velocity at an angle relative to the horizon. Assume the cannon is at the origin and that the ground is flat. The projectile remains in the air for a ``hang time'' and hits the ground a horizontal distance (``range'') away from the origin. The problem is to write a program that:

1. Contains initial values and as constants.
2. Computes the ``hang time'' .
3. Computes the range .
4. Computes the position (x,y) of the projectile for 100 times from to .
