Spaceship ferrying workers to Moon Base problem

  1. Jun 29, 2007 #1
    does any one know how to answer this problem?
    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 for the first time interval 16.0 of the trip, then travels at constant speed until the last time interval 16.0 , when it accelerates at 20.6 , just coming to rest as it reaches the moon.

    What is the maximum speed attained?

    What fraction of the total distance is traveled at constant speed?

    What total time is required for the trip?

    Thread moved from General Physics to Homework Help, Intro Physics.

    Welcome to the PF, 123GO. Homework and coursework questions need to be posted in the Homework Help forums, and you are required to show some of your own work before we can help you.

    So tell us what the relevant equations and concepts are for solving this type of question, and show us how you would start to approach the solution.

    Not the way it is worded. Please don't confuse the OP. It looks to be a straightforward kinematics question.
