Consider a space shuttle which carries life support material from earth to moon. A straight motion with a 384000 km is the closest distance between earth and moon. Assuming the shuttle's acceleration is  20.7 m/s2  for the first time interval 14.6 min of the trip, then travels with a constant velocity until the last time interval 14.6 min , when it accelerates at − 20.7 m/s2 , just coming to rest as it reaches the moon.

a- Find the maximum velocity reached?

b- Which part of the total distance is traveled at constant velocity?

c- How much time needed for the whole trip?
