Chapter 04, Problem 109 The central ideas in this problem are reviewed in Mutiple-Concept Example 9. One block rests upon a horizontal surface. A second identical block rests upon the first one. The coefficient of static friction between the blocks is the same as the coefficient of static friction between the lower block and the horizontal surface. A horizontal force is applied to the upper block, and its magnitude is slowly increased. When the force reaches 40.3 N, the upper...

To practice Problem-Solving Strategy 8.1 Static equilibrium problems. and Felbow. Part 1 When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm is 1.20 kg. If the biceps is connected to the forearm a distance dbiceps = 2.50 cm from the elbow, how much force Fbiceps must the biceps exert to hold a 500 g ball at the end of the forearm at distance...

What is parts B and C?
hwch4,5 xercise 5.33-Enhanced Constants You are lowering two boxes, one on top of the other down the ramp shown in the figure (Figure 1) by pulling on a rope parallel to the surface of the ramp. Both boxes move together at a constant speed of 12 0 cm/s . The coefficient of kinetic friction between the ramp and the lower box is 0.449, and the coefficient of static friction between the two boxes is...
