Three objects each have mass m. Each object feels a force from the other two, but not from any other object. Initially the first object is at x=L, y=0; the second object is at x=+L, y=0; and the third object is at x=0, y=L. The momentum of the system of the particles at the initial time is zero. At a later time the first object is at x=L/3, y=+L/4; and the second object is at x=+L/2, y=L. At this later time, where is the third object? Find the x-position of the third object

Big fish swim substantially faster than small fish, while big birds fly faster than small ones. However, the speeds of runners vary a lot less with body size, although big ones do go somewhat faster, never mind a lot of highly unreliable top speed data. Some general scaling rules might help. Assume that the cost of transport (cost per distance) varies with body mass^0. 68, that the maximum metabolic rate varies with body mass^0. 81, and that efficiencies and so forth don't vary with body size. How many times faster should a 450 kilogram bear be able to run than the top speed of a 45gram rodent
