A van travels a distance d=28 m in the positive x-direction in a time of t=19.5 s. The van immediately brakes and comes to rest in t2=6 s.  What are the van'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 van started from rest and moved with a constant acceleration? What was the van's instanteous velocity in the horizontal direction, in meters per secon
