A 2.8-kg block is attached to a spring with a force
constant of 375 N/m, as shown in the figure(Figure 1).
Find the work done by the spring on the block as the block moves from A to B along paths 1 and 2.
Enter your answers numerically separated by commas. Express your answers using two significant figures.
$W_1, W_2 =$
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.)
increases
decreases
stays the same
