Homework Help: Constant rolling resistance?

  1. May 24, 2007 #1
    A ball rolls across a table and stops due to rolling friction. It has a mass of m and travels a distance of s in the time t.

    What is the ball's initial speed?

    The same ball rolls until it hits a wall. It has a mass m, and travelled a total distance of s (to the wall) in the time t.

    What is the ball's initial speed?

    At what speed does the ball hit the wall?

    I have formulated my question into a textbook-style question since that seems to be the rules here. I just wanted to know if the deceleration of a ball rolling a cross a table is typically constant.

    Yes, if it is the same ball and surface that it rolls on.
