A spaceship ferrying workers to Moon Base I takes a straight-linepath from the earth to the moon, a distance of about 384,000 km.Suppose it accelerates at 21.1m/s2 for the first 12.5 minof the trip, then travels at constant speed until the last12.5 min, when it accelerates at-21.1 m/s2, just coming torest as it reaches the moon.

(a) What is the maximum speed attained?

(b) What fraction of the total distance is traveled at constantspeed?
