Journal 12/18

1. The two forces are drawn to show the forces on the ball and the forces on Chris. Two different objects of reference. Yes, two force diagrams are needed to determine the answer of the question, which is solving for FnetY.

2.Yes, because when finding the FnetY Force - 2000 divided by the gravitational constant that should be equal to the mass.

3. FnetX is non-existent in the force diagrams, which should be there. In the second force diagram, it should be Force of the Ball on Chris rather than Force of Earth on Ball.

  1. You are definitely doing some good thinking about this assignment, but you will need to solve the problem for yourself before you can evaluate Jon's work.
