Statement of a problem № 10281


A 2.8-kg block is attached to a spring with a force constant of 375 N/m, as shown in FIGURE 8-26. (a) Find the work done by the spring on the block as the block moves from A to B along paths 1 and 2. (b) How do your results depend on the mass of the block? Specifically, if you increase the mass, does the work done by the spring increase, decrease, or stay the same? (Assume the system is frictionless.)
