Homework Help: Kinematics question - elevator problem

  1. Sep 8, 2011 #1
    Kinematics question...........?
    you are asked to program a sequence of vertical motions for an elevator to take it from one floor in a building to the floor directly above, a total distance of 5.0m. In order to ensure that the ride is safe and comfortable for passengers, the elevator's motion is subject to the following constraints:

    1. The speed can't be >1.0 m/s
    2. The magnitude of the acceleration can't be > 0.50 m/s^2
    3. The magnitude of the acceleration's rate of change ("jerk") can't be >.50m/s^3

    a. What sequence of motions will get the elevator from one floor to the one directly above as fast as possible?
    b. how much time does the elevator's trip take from one floor to the floor directly above?

    I have some graphs of acceleration and velocity graphs, but i honestly dont really know where to start.

    Units of "jerk" or "surge" are m/s3.
