Sorry this is late. The test is Monday 2008-11-17, keep studying these problems: 10.3, 7, 11, 20, 33, 39, 43; 11.3, 14, 23, 33, 41, 44, 46; 12.5, 15, 26, 30, 36, 44, 48, 55.

Problem 3 on the practice test is the hardest. #5 and #6 assume you know Kepler’s 3rd law, the mass and radius of the earth, G, and the black hole formula. I showed them in the solutions above. Dr. Tulsian should write those on the board during the test, if he picks my problems.

#4 is tricky. Remember the quadratic formula. You can also factor it as (x+1L)(x-3L), and then find that x can equal -1L or 3L. Only the positive answer counts, so the answer is 3L.

Remember that radius is half the diameter.

Good luck.
