CPM Homework Help : PC Problem 10-69

Refer to the problem involving the oyster shell dropped by the gull. For the original situation (wind blowing at $22$ feet per second), determine how far the shell has traveled horizontally when it hits the ground.

Original problem:
$x = 22t$
$y = −16t^2 + 256$

Hint 1:

First, determine how long ( $t$ ) in takes the shell to hit the ground. This is when $y = 0$ .

Hint 2:

Use your solution for $t$ from the previous hint in the $x =$ equation to determine how far the shell has traveled horizontally.
