A pirate shoots a cannonball into the air from a height of 10
Aneli [31]

We are basically given most of what we need to calculate the height of the cannonball.

We use the formula h = –16t+ vt + s to find the height requested.

Let v = 160

Let s = 10

Let t = time in seconds

Was the value of t included? We need to know t to plug into our formula.

You know everything else except for t. Go back to your notes to search for t. Afterward, plug the value of t and everything else given above into the formula and calculate to find h.
