1. You are driving eastbound on the interstate at 70 mi/h . You observe that you are approaching a truck in your lane at a relative speed of 20 mi/h .

a. How fast is the truck moving relative to the highway?

b. If the truck were instead traveling at this speed in the westbound lane, what would be the relative velocity between you and the truck?

2. During an auto accident, the vehicle's air bags deploy and slow down the passengers more gently than if they had hit the windshield or steering wheel. According to safety standards, the bags produce a maximum acceleration of 60g, but lasting for only 31 ms (or less). How far (in meters) does a person travel in coming to a complete stop in 31 ?
