Velocity of a ball rolling down a ramp (and onto the floor)?

  1. Oct 4, 2009 #1
    1. The problem statement, all variables and given/known data

    A ramp is set up so that one end is propped up with a few textbooks and the other end is continuous with the floor. You roll a marble down an incline and onto the floor. Compare the velocity of the marble down the incline with the velocity of the marble as it rolls onto the smooth floor.

    2. Relevant equations

    None needed. The question is just asking for a general shape to the graph or a pattern.

    This is what my velocity graph looks like (higher line is velocity of marble rolling onto smooth floor after going down the ramp, lower is the velocity as it goes down the ramp from the beginning to the end of the ramp): http://img43.imageshack.us/img43/1338/sketchonlyg.jpg [Broken]
    Is this accurate?

    When the ball rolls down the ramp does it accelerate?
    When the ball rolls on the floor, does it accelerate?
    If the answer is "yes" to any of these questions, is the acceleration constant or does it change depending on where the ball is?
