[Load Homework 3.]

A blue ball is circling around a black hole, kept in orbit by the force of gravity. Of course the black hole (as is true of all black holes) can't be seen. Using the applet below, determine the location of the black hole and the mass of the black hole. The mass of the ball doesn't matter, but its actual mass is 2 kg.  Show and explain your work. Use complete sentences when giving your explanations for simulations. Be sure and give the data used in the calculation. You may discuss this problem with others, but your work and explanation must be your own. Warning: You must be using a browser that can run Java. You must wait for the applet to load (a preliminary graph will appear) before clicking "load homework 3"). If you have trouble, try reloading this page.
