Effective force constant of the branch and mass of eagle

Reference no: EM13673027

A 0.45-kg crow lands on a slender branch and bobs up and down with a period of 1.1 s. An eagle flies up to the same branch, scaring the crow away and lands. The eagle now bobs up and down with a period of 3.6 s. treating the branch as an ideal spring, discover (a) the effective force constant of the branch and (b) the mass of the eagle.
