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 car's average velocity in the horizontal direction, in meters per second, during t1? 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? What was the car's instantaneous velocity in the horizontal direction, in meters per second, when it began braking? Using the result from part (c), what was the car's horizontal component of acceleration, in meters per second squared, during the braking period?
