A spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384000km Suppose it accelerates at an acceleration 20m/s? for the first time interval 15min of the trip, then travels at constant speed until the last time interval 15min, when it accelerates at 20m/s?, just coming to rest as it reaches the moon. a) What is the maximum speed attained? b) What fraction of the total distance is traveled at constant speed? c) What total time is required for the trip?
