A golf ball is driven from a tee at ground level to land \( 250 \) yards away. It achieves a maximum height \( 40 \) yards in the air as it travels.
1. Find an equation for the quadratic function this represents. Write your final answer in standard form. 2. There is a tree that is \( 100 \) yards away from the tee. If it's \( 36 \) feet tall, how much will the ball clear it by?
