In the figure here, a small block is sent through point A with a speed of 6.3 m/s. Its path is without friction until it reaches the section of length
L = 13 m, where the coefficient of kinetic friction is 0.73. The indicated heights are h1 = 5.1 m and h2 = 2.0 m. What are the speeds of the block at (a) point B and (b) point C? (c) Does the block reach point D? (d) If so, what is its speed there; if not, how far through the section of friction does it travel?
