1a. 1b. In the figure below, a block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is vo; the height difference is h and the coefficient of kinetic friction is Wk. Find d in terms of the given variables (use g where applicable). u-0- In...
