Answer:
Option (1). 4.64 seconds.
Step-by-step explanation:
It is given in the question that a baseball pitcher was at an initial height of 6 feet.
Velocity of the ball is 73 feet per second.
The expression that represents the event is
H(t) = -16t² + vt + s
Here s = initial height = 6 ft.
H(t) = 0
velocity of the ball = 73 feet per second
The expression will be
-16t² + 73t + 6 = 0
Now we will get the solution for t.
and
Time can not be negative so t = 4.64 sec is the answer.
Option 1). 4.64 is the answer.
