A boat travels to the right in a straight line away from a dock with an average acceleration of 12.0 m/s2. The boat then has it's engine stopped and the boat slows down at the same magnitude as it accelerated until it stops. The boat then turns around and travels back to the dock with the same average acceleration as before. Just as the boat reaches the dock the engine starts on fire. This slows the boat down with the same magnitude as it accelerated until it stops. Explain what the signs of each acceleration and deceleration should be for both traveling away and traveling toward the dock.

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?
