Question

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?

Answer 1

120 m

Step-by-step 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):

`y=0.9x+30\\y=0.9 (100)+30\\y=90+30=120`

Notice also that both quantities in the graph display meters

Therefore: the cannon ball would go 120 meters
