Question

# At serve, a tennis player aims to hit the ball horizontally. What minimum speed is required for the ball to clear the 0.90-m-high net about 15.0 m from the server if the ball is "launched" from a height of 2.50 m? Where will the ball land if it just clears the net (and will it be "good" in the sense that it lands within 7.0 m of the net)? How long will it be in the air?

$y = y_0 + v_{0y}t + \frac{1}{2}at^2$

Use $y$ instead of $x$ for vertical distance to not get confused between
horizontal and vertical displacement.
