5. at the scene of a crime, you find three patterns of blood spots. you measure the following
lengths and widths for each spot:
spot a pattern: length = 4.0 mm, width = 4.0 mm
2. spot b pattern: length = 3.0 mm, width = 1.6 mm
3. spot c pattern: length = 5.0 mm, width = 1.0 mm
use the formula given above (arcsin(width/length))to determine the angle of impact for each of these three bloodstain
patterns. which dropped from a point directly overhead? which impacted at the sharpest angle?
as a blood spatter analyst, how would you interpret and use this information? explain.

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
