A car with a mass of 1375 kg is moving 7.5 m/s [N34E] and collides with another car with a mass of 1700 kg moving 4.5 m/s [S]. The two cars stick together when they collide.
What is the final velocity of both vehicles?

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].
