How long does it take for a basketball to roll 5 meters?

I'm doing a project, but I'm in class right now so I can't collect the necessary data. How long does it take for a basketball to roll 5 meters?|||Hi!


First, you must take in note that the speed is an important factor.


Okay, so all you gotta do is take the circumference of the ball you want. Each ball doesn't have the same circumference. After, all you need to do is 5/measure= number of times the ball rolls on it self on 5 meters. Than the speed is what that makes this problem impossible. Hope this helps.|||Circumference of the ball (according to wikipedia) =29.5 inches = 74.9cm


5 meters = 500 cm


500/ 74.9 = approx 6.68 revolutions


Find how long (s) to make 1 revolution and multiply by 6.68|||It depends on how fast it's rolling.
