A 046-Kg Block Is Held in Place Against the Spring by by a 30-N

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 v1=1.2 m/s. Upon separation from the spring,as shown in the figure.The block descends a ramp and has a velocity v2=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?

A) 0.30 m
B) 0.039 m
C) 0.26 m
D) 0.40 m
E) 0.60 m
