Karla's car is stuck in the mud. Fan and Warren come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Fan and Warren get behind the car and push. The truck generates a horizontal force of 319 lb on the car. Fan and Warren are pushing at a slight upward angle and generate a force of 147 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.3. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 147 lb 20.3 319 lb a a. The resultant force is (Tip: omit degree notations from your answers; e.g. enter cos(45) instead of cos(45)) b. It's magnitude is lb. c. It's angle from the positive x-axis is Submit Question Hint: For a detailed solution, see the example (Finding Resultant Force) in Section 2.1 (Vectors in the Plane).
