Question 1208040: 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) = [(-32x^2)/(130)^2] + x, where x is the horizontal distance that the golf ball has traveled.

Determine the height of the ball after it has traveled 100 feet.

For this problem, I must let x be 100 and simplify.

.

Your thinking (your hypothesis) is correct.

Take the value of x= 100 and substitute it into the given formula for h.

Then calculate h(100).

At the end, check that h(100) is greater than zero.

It will assure that the ball is still in flight and did not get the ground.
