A truck with a mass of 4000 kg traveling with a speed of 10 m/s collides at right angles with a car with a mass of 1500 kg traveling with a speed of 20 m/s.
a. Sketch to proper scale and direction the momentum vectors of each vehicle prior to the collision.
b. Using the graphical method of vector addition, add the momentum vectors to get the total momentum of the system prior to the collision.
