A hoop of mass M = 3 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...

A mass m = 12 kg is pulled along a horizontal floor with NO friction for a distance d =6.5 m. Then the mass is pulled up an incline that makes an angle θ = 25° with the horizontal and has a coefficient of kinetic friction μk = 0.44. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 25° (thus on the incline it is parallel...

A mass m = 14 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.12, for a distance d = 5.9 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 38° with the horizontal. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 38° (thus on the incline it is...
