A marble of mass M and radius R rolls without slipping down the track on the left. The height from the bottom of the track to the center of the marble is h1, as shown in the figure. The marble then goes up the frictionless track on the right, until it reaches a maximum height h2 (again from the bottom of the track to the center of the marble). Note that since the right track is frictionless, the marble's rotational speed remains constant as it rises, even though its translational speed is decreasing! what is h2

A marble of mass M and radius R rolls without slipping down the track on the left. The height from the bottom of the track to the center of the marble is k|, as shown in the figure. The marble then goes up the frictionless track on the right, until it reaches a maximum height h; (again from the bottom of the track to the center of the marble). Note that since the right track is frictionless, the marble's rotational speed remains constant as it rises, even though its translational speed is decreasing!
