The initial velocity of the center of mass of the system is zero. Find the magnitude ?S of the star's displacement from the origin in its final position.

Sphere A with mass 70 kg is located at the origin of an xy coordinate system; sphere B with mass 73 kg is located at coordinates ( 0.23 m, 0); sphere C with mass 0.55 kg is located at coordinates ( 0.15 m, 0.14 m). In unit-vector notation, what is the gravitational force on C due to A and B?

Migrating land mammals are often called runners because of the large distances that they can cover in one day. The velocity (speed) of a migrating land mammal or runner in relation to its mass can be modeled by the equation V(m) = 9.31m0.12, where m is the mass of the animal in kilograms and V is the velocity in kilometers per day. Round your answers to the tenths place, if necessary. Part A: Complete the table by determining the velocity of several different runners.
