Darcel and Chandra are sitting in the park after physics class,
and they notice some children rolling various objects down a slight
incline in the sidewalk. Darcel is curious how the masses and
shapes of the objects affect their motion, and Chandra says that it
might be fun to think about the energy of motion associated with
rolling objects. The friends decide to use the simulation to
explore the motion and energies of various objects rolling down an
incline.

3. In this question you will do some algebra to determine two relations that you will need for Part 2 of this lab. Write down Eq. 11 twice. In the first statement, set the rotational kinetic energy term equal to zero (i.e. 1/2lo 0) -call this your "No Krot model". Leave the second as it is written in Eq. 11 call this your "Krot model". For both models, solve for v in terms of g, h, and a. In...
