Physics

A 575-g block is dropped onto a relaxed vertical spring that hasa spring constant k =200.0 N/m. The block becomes attached to thespring and compresses the spring 58.1 cm before momentarilystopping. While the spring is being compressed, what work is doneon the block by the gravitational force on it?What is the speed ofthe block just before it hits the spring? (Assume that friction isnegligible.)

If the speed at impact is doubled, what is the maximumcompression of the spring?
