Question
A 1.86-kg block is held in place against the spring by a 81-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
%3D
B. The block enters a rough section at B, extending to E. The coefficient of kinetic
friction over this section is 0.28. The velocity of the block is v3 = 1.4 m/s at C. The
block moves on to D, where it stops. The height h of the ramp is closest to
