Question

5.) (1 point) Ms. Marvel detects two gigantic asteroids traveling through space which will collide and send them on a trajectory to destroy the Earth. When they collide, she calculates that the 3-component vector describing the direction of their impact force are: 3 a = 1-51 12.5) -- and a2 = 2 11.25) Her plan is to blast the asteroids at the point where they meet to cause them both to remain absolutely still. What vector will describe the force she needs to accomplish her task?
