The platform on the phet simulation could only go 15 meters above ground.

calculate how far the cannon ball would go if we shot it off a platform of 100 meters tall?

120 m

Explanation:

Simply use the given equation that represents how far the cannon ball would go in terms of the height of the platform. That is: use 100 m for "x" (platform height) in the equation to find "y" (the distance the cannonball would go):

Notice also that both quantities in the graph display meters

Therefore: the cannon ball would go 120 meters

volume: 22

density: 7.04
