A 625 gram block is dropped onto a vertical spring with spring constant k =160.0 N/m. The block becomes attached to the spring, and the spring compresses 81.7 centimeter before momentarily stopping.
While the spring is being compressed, find what work is done on the block by its weight?
While the spring is being compressed, find what work is done on the block by the spring force?
Find the speed of the block just before it hits the spring? (Suppose that friction is negligible.)
If the speed at impact is doubled, calculate the maximum compression of the spring?
