Determine how far will the spring stretch

Reference no: EM13669124

When a 5.00 kilogram object is hung vertically on a certain light spring that obeys Hooke's law, the spring stretches 2.80 centimeter.

(a) If the 5.00 kilogram object is removed, find how far will the spring stretch if a 1.50 kilogram block is hung on it?

(b) Find how much work must an external agent do to stretch the same spring 4.00 centimeter from its unscratched position?
