A 0.46-kg block is held in place against the spring by a 30-N horizontal external force. The external force is removed, and the block is projected with a velocity v1= 1.2 m/s upon separation from the spring, as shown in the figure. The block descends a ramp and has a velocity v= 1.5 m/s at the bottom. The track is frictionless between points A and B. The block enters a rough section at point B, extending to E. The coefficient of kinetic friction between the block and the rough surface is 0.38. The velocity of the block is v3 1.4 m/s at point C. The block moves on to D, where it stops. What distance does the block travel between points B and D? Smooth D B Rough 0.30 m 0.60 m 0.40 m 0.26 m 0.039 m
