A force of 30 N acts in a direction N60degreesW on a barge of 1000 kg, which is moving due west at 1.5m/s in a canal.
What is the magnitude and direction of the frictional forces applied to the barge by the water?
the Samsung Solstice is listed with aGPS. I wonder if you can install Third Party GPS software into the phone like Garmin Mobile XT or Tom Tom Navigator? I searched through the Internet but cant seem to find anything about this.
