Multiple Choice
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 upon separation from the spring, as shown in the figure. The block descends a ramp and has a velocity 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 at point C. The block moves on to D, where it stops. What distance does the block travel between points B and D?
A) 0.30 m
B) 0.039 m
C) 0.26 m
D) 0.40 m
E) 0.60 m
