Consider to cars traveling directly towards each other. car a has twice the mass of car b. in order for the cars to completely stop when they collide, which of the following is true? (remember, momentum = mass * velocity) car a should have twice the velocity of car b car b should have twice the velocity of car a car a should have 4x the velocity of car b car b should have 4x the velocity of car a

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].
