Assume a uniform cylinder rolls without slipping on a horizontal surface. Assume the cylinder has a mass of 2.0 kg and a radius 0.5 m. If during 1.0 s the center of mass undergoes 0.2 m of translation, how many meters does a point on the rim of the cylinder travel during that same time?

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
