During a trial run, race car a starts from rest and accelerates uniformly along a straight level track for a particular interval of time. race car b also starts from rest and accelerates at the same rate, but for twice the time. at the end of their respective acceleration periods, which of the following statements is true? car a has traveled a greater distance. car b has traveled twice as far as a. car b has traveled four times as far as car a. both cars have traveled the same distance.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
