Answer:
31 feet.
Step-by-step explanation:
It is mentioned in the question that
Height of baseball expressed in feet
T = time in seconds
Also
Now the time is 3.5 so put this value to the above equation
h = -16(3.5)^2 + 64(3.5) + 3
= -16(2.25) + 224 + 3
= -196 + 227
= 31
Therefore the height of a baseball is 31 feet and the same is to be considered
