Problem 15.43 5 of 13 Review The 20-g bullet is travelling at 400 m/s when it becomes embedded in the 2-kg stationary block. The coefficient of kinetic friction between the block and the plane is Me = 0.2. (Figure 1) Part A Determine the distance the block will slide before it stops. Express your answer to three significant figures and include the appropriate units. A ? S = Value Units Submit Request Answer Provide Feedback Next > Figure < 1 of 1 > 400 m/s
