Analyze the graph of a cannonball launched from the ground with an initial velocity of 144 feet per second. The cannonball reach
MrRissso [65]
We can find that the formula is:
h(t)=-16t^2 + 144t

We are told that the cannonball reaches its maximum height at t = 4.5 seconds. To find the maximum height, let's just plug this into the formula:
h(4.5) = -16(4.5)^2 + 144(4.5) = 324

The height is 324 feet. We're done!
