Please help me how to do this.

35. Motion of a Golf Ball
A golf ball is hit with
an initial velocity of
130 feet per second at an
inclination of 45° to the
horizontal. In physics, it
is established that the
height h of the golf ball
is given by the function
h(x)
=
-32x²
130²
+ x
where x is the horizontal
distance that the golf ball
has traveled.
(a) Determine the height of the golf ball after it has traveled
100 feet.
(b) What is the height after it has traveled 300 feet?
(c) What is h (500)? Interpret this value.
(d) How far was the golf ball hit?
(e) Use a graphing utility to graph the function h = h(x).
(f) Use a graphing utility to determine the distance that the
ball has traveled when the height of the ball is 90 feet.
0 and ATbl = 25. To
(g) Create a TABLE with TblStart
the nearest 25 feet, how far does the ball travel before
it reaches a maximum height? What is the maximum
height?
(h) Adjust the value of ATbl until you determine the distance,
to within 1 foot, that the ball travels before it reaches its
maximum height.
