In tennis, one of the primary ways to win a point is by making the ball bounce twice on your opponent's side of
the court. A tennis player hits a ball at a velocity of 50
m/s at a 0 degree angle from 1m high. When the ball
bounces it reflects its velocity angle perfectly and loses
30% of its speed.

How long does the other player have to return the ball
before the second bounce?
