I'm really having trouble with 3 word problems.

I won't post all three in one thread, but here's the first one.

==========================================

Question:A golfer hits a ball off the tee at 42m/s. The flag is 183m from the tee in the centre of the green, and the green is round with a radius of 9m. Assume the ball went in the right direction.

Did it land on the green? For this problem use the quadratic function:

y=x- 9.8x²--------------------------> (so that's y=x-9.8² OVER v²)

......... v²

Where x is the horizontal distance, y is the height of the ball above the ground, and v is the initial velocity of the ball.

======================

Here's what I drew on my paper (remade it online to show you guys)
