A spaceship ferrying workers to Moon Base I takes a straight-line path from the earth to the moon, a distance of 384,000 km. Suppose it accelerates at an acceleration 20.6 m/s^2 for the first time interval 15.7 min of the trip, then travels at constant speed until the last time interval 15.7 min, when it accelerates at -20.6 m/s^2, just coming to rest as it reaches the moon.
What is the maximum speed attained?
What total time is required for the trip?
I have tried so many ways to find the correct answer but i can't seem to do it right....please help
