A majorette in a parade is performing some acrobatic twirlingsof her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm. 
With a skillful move, the majorette changes the rotation ofher baton so that now it is spinning about an axis passing throughits end at the same angular velocity 3.00 rad/s as before. What is the new angularmomentum of the rod?

In basic high school physics/calculus you learn that you can formulate equations for velocity and displacement under constant acceleration as:
a ( t ) = a 0
v ( t ) = a 0 t + v 0
x ( t ) = 1 2 a 0 t 2 + v 0 t + x 0
My question is how would you formulate a similar equation when acceleration is dependent on the inverse-square of distance from a point, such as Coulomb's Law or Isaac Newton's inverse-square law of universal gravitation?
