In an automobile safety test, a shoulder and seat belt exerts a force of 84.0 lb directly backward and a force of 78.0 lb backward at an angle of 18° below the horizontal on a dummy. If the belt holds the dummy from moving farther forward, what force did the dummy exert on the belt? 84.0 lb Set up the problem by representing each force as a vector, using an angle given from standard position. Let A represent the 84.0 lb force, and let B represent the 78.0 lb force. Vector Standard-position Angle Magnitude lb A O B lb the horizontal. The dummy exerted a force of (Round to one decimal place as needed.) lb, at an angle of O 78.0 lb 18⁰
