A car travels a distance d = 29 m in the positive x-direction in a time of t1 = 21.5 s. The car immediately brakes and comes to rest in t2 = 7 s.Randomized Variablesd = 29 mt1 = 21.5 st2 = 7 s What was the acceleration, in meters per second squared, during time interval t1, assuming the car started from rest and moved with a constant acceleration? Using the result from part (c), what was the car's horizontal component of acceleration, in meters per second squared, during the braking period?
Jane is driving down the road at 20.0 m/s looking for a house address. when she sees the house, she slams on her brakes. If her reaction time is 1.20s and her car deaccelerates at 3.50 m/s^2, how far past the point where she first saw the house did her car come to rest? I feel like I need to use one of the 4 kinematics equations, but none seem to be giving me the correct answer when I plug in my numbers :(

Suppose the caravan of 10 cars begins immediately in front of the first toll booth, travels 20 km to a second toll booth, then another 40 km to a third toll booth, and finally stops immediately after the third tool booth. Thus, they travel a total of 60 km. What is the total end-to-end delay? Where is the last car in the caravan after one hour? Your answer must include a distance/specific location, and not only a relative direction.
