Question

Analyze the graph of a cannonball launched from the ground with an initial velocity of 144 feet per second. The cannonball reached its maximum height after 4.5 seconds. What was the maximum height the cannonball reached?

Answer 1

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!

Answer 2

Answer:

324 feet
