1 1. The force exerted by a linear spring is proportional to the displacement fromits rest length (F = k-X). For the spring depicted below, the sketch at the top isthe rest length, and the sketch on the bottom shows the spring compressedby 2.0 cm just prior to shooting off a BB pellet. The spring constant, k, is2.1x105 N/m.a.cm (hint: calculus)?What is the work required to compress this spring by 2.0If the BB pellet masses 3.0 g, and you fire the BB pelletb.horizontally, what is its' "muzzle velocity?"K 2.0 cm >

Given, spring constant k=2.1×105 N/mcompressed distance =2.0cm
