The 54-lb block rests on the rough surface for which the coefficient of kinetic friction is μk = 0.2. A force F=(40+s2)lb, where s is in ft, acts on the block in the direction shown. The spring is originally unstretched (s= 0) and the block is at rest. (Figure 1) Figure 1 of 1A picture shows a block laying on a horizontal surface with a spring of stiffness k equal to 20 pounds per foot attached to its right side. The other end of the spring is pressed against the wall. Force F is pushing the block to the right and downwards, at an angle of 30 degrees below the horizontal.
