... If you were to tunnel into a star (star stays the same size), the gravitational force you experience depends on the amount of mass in a sphere of radius equal to your distance from the star's center, and on your distance from the center. Now the amount of mass in that sphere is proportional to volum ...

Newton`s Second Law, X
... Plan: Since both forces and velocity are involved, this problem requires both the equation of motion and kinematics. First, draw free body diagrams of A and B. Apply the equation of motion to each. Using dependent motion equations, derive a relationship between aA and aB and use with the equation of ...
