Reference no: EM13717529

Compute all parts of given problem:

Problem: When a 4.30-kg object is hung vertically on a certain light spring that obeys Hooke's law, the spring stretches 2.20 cm.

Part I: If the 4.30-kg object is removed, how far will the spring stretch if a 1.50-kg block is hung on it?

Part II: How much work must an external agent do to stretch the same spring 4.00 cm from its unscratched position?

This is a physic problem, reply as soon as possible. Thanks.
