A wheel in the shape of a flat, heavy, uniform, solid disk is initially at rest at the top of an inclined plane of height 2.00 m when it begins to roll down the incline. If rolling and sliding friction are neglected, what is the linear velocity, in m/s, of the center-of-mass of the wheel when it reached the bottom of the incline?
Two identical wheels are moving on horizontal surfaces. The center of mass of each has the same linear speed. However, one wheel is
rolling, while the other is sliding on a frictionless surface without rolling. Each wheel then encounters an incline plane. One continues
to roll up the incline, while the other continues to slide up. Eventually they come to a momentary halt, because the gravitational force
slows them down. Each wheel is a disk of mass 4.00 kg. On the horizontal surfaces the center of mass of each wheel moves with a linear
speed of 5.47 m/s. (a), (b) What is the total kinetic energy of each wheel? (c), (d) Determine the maximum height reached by each wheel
as it moves up the incline.
