1. The problem statement, all variables and given/known data "SpaceForce One" is a perfectly spherical ship of mass 2.5·10^6 kg and Radius 42 meters bobbing up and down in calm seas on Earth At what frequency does SpaceForce ship bob? 2. Relevant equations None explicitly given. 3. The attempt at a solution We approached this problem in a number of ways. We really struggling with making assumptions (we are given quite a bit of liberty to make approximations) that make the problem solvable. We can pretty easily solve the problem if it's a cylinder, but we are having a lot of issues accounting for the change in volume of the sphere. What would be some helpful assumptions to make? Any hint in the right direction is appreciated. Thanks!
