Rolling Motion Up and Down an Incline (a) A rolling (without slipping) hoop with a radius of 0.10 m and a mass of 1.80 kg climbs an incline. At the bottom of the incline, the speed of the hoop's center-of-mass is v. = 7.00 m/s. The incline angle is NOT needed in this problem. Vf=0 Max h What is the angular speed of the hoop's rotation?

A hoop of mass M = 2 kg and radius R = 0.4 m rolls without slipping down a hill, as shown in the figure.
A hoop of mass M = 2 kg and radius R = 0.4 m rolls without slipping down a hill, as shown in the figure. The lack of slipping means that when the center of mass of the hoop has speed v, the tangential speed of the hoop relative to the center of mass is also equal to VCM, since in that case the instantaneous speed is zero for the part of the hoop that is in contact with the...

Solve for the final angular velocity (ans. 22.9 rad/s)
Let's look at a new example to see how this works. Consider a solid wheel of radius 0.5 m and mass of 2 kg. The wheel sits at the top of a hill that has a height of 10 m. Starting from rest, the wheel rolls without slipping down the hill to the bottom. What is the velocity of the wheel at the bottom of the hill? The key to this...
