Is Rolling Resistance Constant When a Ball Rolls Across a Table?

Click For Summary
SUMMARY

The discussion centers on the concept of rolling resistance and its effect on a ball rolling across a table. It establishes that the deceleration of a ball due to rolling friction is typically constant when the same ball and surface are used. The mass of the ball (m), the distance traveled (s), and the time taken (t) are critical variables in determining the ball's initial speed and the speed at which it hits a wall. The conclusion confirms that under consistent conditions, rolling resistance remains constant.

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 traveled 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.
