5. A golf ball is hit from the top of a tower that is 24 m high. The ball follows
a parabolic path
defined by the function,
ℎ(𝑡) =
-5t
2
+14t+24
, where
𝑡 represents the time in seconds
since the ball
was hit, and
ℎ(𝑡) represents the height of the ball above the ground in metres. Algebraically
determine how long the ball is in the air.
