Consider a person standing in an elevator that is moving at constant speed upward. the person, of mass m, has two forces acting upon him, the downward force m g due to gravity, and the upward supporting force n exerted by the floor of the elevator. in this case, which of these two forces has the smaller magnitude?

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].
