The number of seconds that the ball will hit the ground will be 6 seconds.

<h3>What is kinematics?</h3>

It is the study of the motion of a body without considering mass. And the reason behind them is neglected.

A ball is thrown vertically upward with an initial speed of 96ft/sec. Its height after t seconds is given by

h = - 16(t - 3)² + 144

Then the number of seconds that the ball will hit the ground will be

When the ball is on the ground, the height of the ball is zero. Then we have

          0 = - 16(t - 3)² + 144

16(t - 3)² = 144

   (t - 3)² = 9

      t - 3 = 3

           t = 6

More about the kinematics link is given below.

Hi can some please help?
Oduvanchick [21]
So I'm assuming that you're taking Calculus.
The first thing you want to do is take the integral of f(x)...
Use the power rule to get:
4X^2-13X+3.
Now solve for X when f(x)=0. This is because when the slope is 0, it is either a minimum or a maximum(I'm assuming you know this)
Now you get X=0.25 and X=3. Since we are working in the interval of (1,4), we can ignore 0.25
Thus our potential X values for max and min are X=1,X=4,X=3(You don't want to forget the ends of the bounds!)
Plugging these value in for f(x), we get
f(1)=2.833
f(3)=-8.5
f(4)=1.667
Thus X=1 is the max and X=3 is the min.
So max:(1,2.833)
min:(3,-8.5)

Hope this helps!
