Rolling Without Slipping - Real World Physics Problems

Rolling without slipping commonly occurs when an object such as a wheel, cylinder, or ball rolls on a surface without any skidding. To define such a motion we have to relate the translation of the object to its rotation. For example, let’s consider a wheel (or cylinder) rolling on a flat horizontal surface, as shown below.
