WebMar 23, 2015 · In the third case the target ball is placed on a plane with friction (plane B in figure 9(B)). The target ball departs from the collision sliding on the plane, but along the motion kinetic friction produces a decrease in linear velocity and an increase in rotational velocity, until the pure rolling condition is reached. Consider a rope where equal forces (e.g., ) are exerted on both sides. By this the rope is stretched a bit and an internal tension is induced ( on every position along the rope). The rope is wrapped around a fixed item such as a bollard; it is bent and makes contact to the item's surface over a contact angle (e.g., ). Normal pressure comes into being between the rope and bollard, but no friction occur…
