# Drop shot 1

A "drop shot" in tennis is a shot that barely passes the net and touches the other side of the court close to the net. This makes it difficult for the opponent to reach the ball if the opponent starts running for the ball from the baseline.

Suppose you hit a drop shot $$3.6\text{ m}$$ from your side of the court, making the ball leave your racket very close to the ground. The ball then clears the net at a height of $$1\text{ m}$$ and touches the ground $$0.9\text{ m}$$ from the net on the opponent's side, as shown in the diagram.

How long (in seconds) is the ball in the air before hitting the ground after you hit the drop shot, to 2 decimal places?


Details and Assumptions:

• Neglect air resistance.
• The plane containing the trajectory of the ball is perpendicular to the net.
• Use $$g = 10 \text{ m/s}^2$$.
