Question
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 v1=1.2 m/s upon
separation from the spring. The block descends a ramp and has a velocity v2=1.9 m/s 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 v3=1.4 m/s at C. The block moves on to D, where it stops. The spring constant of the spring is
closest to
