. A 4000-kg truck traveling with a velocity of 10 m/s due north collides head-on with a 1200-kg car traveling with a velocity of 20 m/s due south. The two vehicles stick together after the collision. a. What is the momentum of each vehicle prior to the collision? b. What are the size and direction of the total momentum of the two vehicles after they collide? E17. For the two vehicles in exercise 16: a. Sketch to scale the momentum vectors of the two vehicles prior to the collision. b. Add the two vectors on your sketch graphically. ONLY solve question 17, but use question 16 to help solve. Answer question 17 correctly and fully. Solve it with the correct formula.
