In the figure below, a small block is sent through point A with a speed of 9.5 m/s. Its path is without friction until it reaches the section of length L = 12 m, where the coefficient of kinetic friction is 0.70. The indicated heights are h1 = 7.4 m and h2 = 2.5 m. (a) What is the speed of the block at point B? m/s (b) What is the speed of the block at point C? m/s (c) Does the block reach point D? If so, what is its speed there and if not, how far through the section of friction does it travel? in units of m or m/s? ? B
