5 = 16t² + 22t + 6
Jen served the final point before winning her tennis match! She tossed the ball up into the air
from a height of 5 feet with a velocity of 22 feet per second. After the ball started to come
back down, Jen hit the ball with her racket at a height of 6 feet.

Which equation can you use to find how many seconds the ball was in the air before Jen hit
it?
If an object travels upward at a velocity of v feet per second from s feet above the ground,
the object's height in feet, h, after t seconds can be modeled by the formula
h = -16t² + vt + s.
6 16t² + 22t + 5
