In the figure here, a small block is sent through point A with a speed of 6.9 m/s. Its path is without friction until it reaches the section of length L = 13 m, where the coefficient of kinetic friction is 0.76. The indicated heights are h1= 6.0 m and h2 = 2.4 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? %3D D (a) Number Unit (b) Number Unit (c) (d) Number Unit B.
