A football player kicks a ball into the air. The ball’s path can be modeled by the relation:
h = -0.04(d – 19)^2 + 14.44
Where h is the ball’s height and d is the ball’s distance from the kicker, both in metres.
QUESTIONS
A) What is the ball’s maximum height reached by the ball?
B) Express the relation in standard form and in intercept form.
C) What horizontal distance will the ball travel before it lands?
D) The goalposts are 35m away and the crossbar is approximately 3m high. Will the ball clear the crossbar?
I’m terrible at these questions, and not sure how to approach or set-up to solve these questions.
If someone could provide guidance for this example, I can use it as a template for my school problems, which I have several similar to this one.
Thank you.
