2.36: a) The truck’s position as a function of time is given by x T = v T t , with v T being the truck’s constant speed, and the car’s position is given by x C = (1/2) a C t 2 . Equating the two expressions and dividing by a factor of t (this reflects the fact that the car and the truck are at the same place at
