An 080-Kg Block Is Held in Place Against the Spring by by a 67-N

question 12

Multiple Choice

An 0.80-kg block is held in place against the spring by a 67-N horizontal external force (see the figure) .The external force is removed,and the block is projected with a velocity upon separation from the spring.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 B,extending to E.The coefficient of kinetic friction over this section is 0.39.The velocity of the block is at C.The block moves on to D,where it stops.The spring constant of the spring is closest to

• A) 3900 N/m.
• B) 2600 N/m.
• C) 2000 N/m.
• D) 1600 N/m.
• E) 1100 N/m.
