Physics

A 320 g block is dropped onto a relaxed vertical spring that hasa spring constant of k = 1.8 N/cm (see the figure). Theblock becomes attached to the spring and compresses the spring 10cm before momentarily stopping. While the spring is beingcompressed, what work is done on the block by (a)the gravitational force on it and (b) the springforce? (c) What is the speed of the block justbefore it hits the spring? (Assume that friction is negligible.)(d) If the speed at impact is doubled, what is themaximum compression of the spring?
