1. Kyle is driving his car at 15 m/s when he noticed that he is approaching a stalled truck that is approximately 35 m away. He steps on the brakes and the car stops 1 m away from the stalled truck. At what rate did the car slow down? Assume that Kyle's reaction time is 0.20 s. Reaction time is the time for the person to notice, think, and act in response to a given situation. 4 т 35 т
