Assignment:
A 230 g block is dropped onto a relaxed vertical spring that has a spring constant of k = 2.5 N/cm. The block becomes attached to the spring and compresses the spring 14 cm before momentarily stopping.
- What work is done on the block by the spring force while the spring is being compressed? (in J)
- What is the speed of the block just before it hits the spring? (Assume that friction is negligible.) (in m/s)
- If the speed at impact is doubled, what is the maximum compression of the spring? (in m)
Provide complete and step by step solution for the question, use formulaes.
