A 250 gm block dropped onto a relaxed vertical spring that has a spring constant of 250
Nt/m. The block becomes attached to the spring and compresses the spring 12 cm before
momentarily stopping.
a) What is the speed of the block just before it hits the spring? Neglect friction.
b) If the speed of impact is doubled, what is the maximum compression of the spring?
