Question
After being kidnapped and placed in the trunk of a car, you find out you are able to pry open the trunk. Luckily your smart phone has a global positioning system (GPS) that receives signal when you open trunk. The GPS tells you that you're moving 35.0 mph in a direction 66.0 degree north of east at a location 1.33 miles west of the police station. You next close the trunk so as not to be spotted. Five minutes later you take another reading that tells you are now 2.1 miles north of the police station and are moving east at a speed of 10.0 mph.
a) What was your average velocity throughout this trip?
b) What was your average acceleration throughout this trip?
c) What is distance and direction you would require to travel to return to the position of your first GPS reading if you jumped out of the car now?
