Vehicle #1 collides into the rear a stopped vehicle (vehicle #2). the following facts about the collision are known: 1. vehicle #1 brakes and skids 150 feet, then impacts the stopped vehicle #2. test skids on the dry, level pavement indicate a drag factor of 0.85 vehicle #1 is traveling 40 mph at the moment that it collides with vehicle #2. after impact, the two vehicles stay together and come to final rest. answer the following questions about this collision, showing your calculations. what is the initial velocity of vehicle #1 at the beginning of the skid marks (i.e., onset of braking)? a. assuming a 1.0 second perception-reaction time for the driver of vehicle #1 and that this driver locked his brakes at the end of this time, how far was vehicle #1 from the initial contact point with vehicle #2 when the driver reached the point of perception? b. how far had vehicle #1 skidded after the first ½ second of skidding? c. what was the speed (in mph) of vehicle #1 after 1.0 second of skidding? d. if vehicle #1 came to a complete stop in 20 feet after the collision, what would its rate of deceleration be after impact? e. f. using the deceleration rate calculated in part e, how much time elapsed from the moment of impact until vehicle #1 came to rest?
