1. What is the location, relative to the center of
the Sun, of the CG of the Sun-Jupiter system?
You may look up needed data to perform this calculation. Comment on whether or not this CG lies within
the Sun itself.
2. Consider a meter stick (fulcrum located at the
30 cm mark) that is balanced. The mass
of the meter stick is centrally located and is 75 g. What is the smallest mass that will balance
the stick?
3. Write out your own definition for “energy.”
BONUS:
Consider a 10-feet long 100-lb beam supported on each by
cables. If a 150-lb person is sitting on
the beam, 3.5-feet from the left end, what is the tension in each cable? Believe it or not, this can be treated like a
(slightly complex) lever problem.
