2005年10月12日，我国成功发射了“神州”六号载人飞船，这标志着中国人民又迈出了具有历史意义的一步．已知火箭的起飞重量M是箭体（包括搭载的飞行器）的重量m和燃料重量x之和．在不考虑空气阻力的条件下，假设火箭的最大速度y关于x的函数关系式为：y=k[ln(m+x)-ln(
2
m)]+4ln2(其中k≠0)．当燃料重量为(
e
-1)m吨（e为自然对数的底数，e≈2.72）时，该火箭的最大速度为4（km/s）．
（1）求火箭的最大速度y（km/s）与燃料重量x吨之间的函数关系式y=f（x）；
（2）已知该火箭的起飞重量是544吨，是应装载多少吨燃料，才能使该火箭的最大飞行速度达到8km/s，顺利地把飞船发送到预定的轨道？
