Apedestrian is crossing walnut street, heading east, when she is struck by a northbound suv on walnut street. the angle of movement between the suv and pedestrian (i. e., angle of impact) is 90 degrees. the pedestrian is walking at an average speed of 4.5 feet per second, and the point of impact between the pedestrian and suv is 32 feet from the west curb of walnut street. the following additional facts about the collision are known: the suv skidded 150 feet before impact and continued skidding until it came to a stop 75 feet beyond the point of impact. test skids indicate a drag factor of 0.80 on the dry, level pavement surface the suv driver's perception-reaction time to fully apply the brakes was 1.0 seconds answer the following questions about this collision, showing your calculations. a. what was the distance between the point of impact and the initial point of perception? b. how far from the point of impact was the suv, after the driver had been braking for 2.0 seconds? assuming that the suv had been traveling at a constant speed prior to braking for the pedestrian, how far was the suv from the point of impact when the pedestrian first stepped off the curb into the street? d. how far had the pedestrian walked into the street when the suv driver first applied his brakes (i. e., the suv began to skid)? e. at what speed did the suv impact the pedestrian? f. how far did the suv skid during the first 1.0 seconds of braking? g. how long was the suv skidding, before and after impact, until it came to a stop?
