A car travels along a straight east-west road. A coordinate system is established on the road, with x increasing to the east. The car ends up 12 mi west of the intersection with Mulberry Road. If its displacement was -24 mi , how far from Mulberry Road did it start? On which side of Mulberry Road did it start? If the trip took 45 minutes, what average speed did the car have during the trip?

Jason ("J"), parked by the side of an east-west road, is watching a car driven by Priscilla ("P"), which is moving in a westerly direction. Selene ("S"), driving east at a speed of 15 m/s relative to Jason, watches the same car. Take the easterly direction as positive. a) If Jason measures a speed of 20 m/s for car P, what velocity will Selene measure? b) If Jason sees Priscilla brake to a halt in 10s, what acceleration (assumed constant)...
