Tennis Net Heights

Will a tennis ball served horizontally?
Will a tennis ball served horizontally at 100 km / h from a height of 2.2 million, a net clear 0.9m high and 10 meters? Solve in two different ways. Please help! I have tried to solve this problem, but can not alone there = (.
100 km / h = 27.8 m / s at that speed, how long does it take to reach the network. t = 10m / 27.8 m / s = 0.36 sec, how long does it take a stone from 2.2 m to 0.9 m was to drop or for how long and 1.3 m height? t = √ (2d / g) = 0.52 second. So it is clear the net. Another way is, as far as in 0.36 sec d = ½ gt ² M = 0.64, less than 1.3 m drop. So it is clear the net. .
