6. Ann is driving down a street at 15 m/s (about 35 mph). Suddenly a child runs into the street. It
takes Ann 0.75 seconds to react and apply the brakes.
A) how many meters will she have moved before she begins to slow down?

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].
