Amir pitches a baseball at an initial height of 6 feet, with a velocity of 73 feet per second. if the batter misses, about how long does it take the ball hit the ground?
hint: use h(t) = −16t2 + vt + s.
answer (1) 4.64 seconds
answer (2) 2.94 seconds
answer (3) 2.28 seconds
answer (4) 0.08 second

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.
