Answer:

Therefore the maximum height that the reach is 49 feet after 1.75 seconds.

Step-by-step explanation:

Given that,

A ball is thrown vertically upward. After t seconds its height is given by the function

h=56t-16 t^2

where h is height in feet.

Maximum value:

Given function f(x)= at²+bt+c.

  1. Find the value -\frac{b}{2a}
  2. Putting x= -\frac{b}{2a} in the given function.
  3. The maximum value of the given function is f(-\frac{b}{2a}).

Here a= -16 ,  b=56 and c=0

The ball attains its maximum height when t=-\frac{56}{2.(-16)}=1.75 s.

Putting the value of t in the given function

h=(56\times 1.75)-16(1.75)^2

  =49 feet

Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
