Homework Help: College Physics (repost)

Posted by Jenna on Monday, October 12, 2009 at 10:33pm.

A 4.1 kg block is attached to a spring with a force constant of 550 N/m , as shown in the figure.

Find the work done by the spring on the block as the block moves from A to B along paths 1 and 2.

W=?

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.)

?

Some help plz i'd very much appreciate it.
