Imagine a rocky asteroid moving at 25 km/s, how big does it have to be to create a magnitude 9.5 earthquake?

Homework #3 (25 Points) Due Thursday Mar. 15

 Chapter Problems Chapter 6 (Page 173) 5 Chapter 7 (Page 201) 2, 5 Chapter 8 (Page 233) 2, 6

Extra Credit (5 Points): Follow the artificial satellite link and use the resources you find to choose a man-made satellite to observe yourself. Then go out and watch it. (The International Space Station is very striking, if it passes within view.) Record and report the object you observed, the time and date of observation, the weather conditions at the time of observation, and the visual appearance of the object - both its brightness and how it appears to move along the sky.
Note: this requires some planning on your part, and many potentially observable satellites are not so easy to see in the Metro area because of light pollution.
