A tennis player standing 8.0 meters from the net hits a ball 1.5 meters above the ground toward her opponent. The ball leaves her racquet with a speed of 25.0m/s at an angle of 14.0 degrees above the horizontal. The net is 1.0 meters high. The baseline is 12 meters back from the net; a ball striking the ground beyond the baseline is out of play
The Attempt at a Solution
I attempted to solve for t using the quadratic equation in conjunction with the above formula for y. I ended up with two solutions, neither was extraneous from what I could tell. I plugged both in for x and ended up with two answers. One was slightly more than 8 (meaning that the ball landed in), the other was a little over 21 (meaning that the ball landed out). I am lost, which is it and how do I know?
