Question: A 1.1-kg object is suspended from a vertical spring whose spring constant is 120 N/m. (a) Find the amount by which the spring is stretched

A 1.1-kg object is suspended from a vertical spring whose spring constant is 120 N/m.
(a) Find the amount by which the spring is stretched from its unstrained length.
(b) The object is pulled straight down by an additional distance of 0.20 m and released from rest. Find the speed with which the object passes through its original position on the way up.
