Graphing Another Cannonball
The function defined by d-50 +312r-16r² gives the height in feet of a cannonball seconds after the
ball leaves the cannon.
1. What do the terms 50, 312t, and - 16 tell us about the cannonball?
2.
Use graphing technology to graph the function. Adjust the graphing window to the following
boundaries: 0 3. Observe the graph and:
a. Describe the shape of the graph. What does it tell us about the movement of the
cannonball?
b. Estimate the maximum height the ball reaches. When does this happen?
