Homework Help: Physics

Posted by Mario on Monday, October 5, 2009 at 9:35pm.

A 290 g block is dropped onto a relaxed vertical spring that has a spring constant of k = 2.6 N/cm. The block becomes attached to the spring and compresses the spring 10 cm before momentarily stopping.

(a) While the spring is being compressed, what work is done on the block by the gravitational force on it? J

(b) What work is done on the block by the spring force while the spring is being compressed? J

(c) What is the speed of the block just before it hits the spring? (Assume that friction is negligible.) m/s

(d) If the speed at impact is doubled, what is the maximum compression of the spring? m
