A car is being pulled out of the mud by two forces that are applied by the two ropes. The dashed line in the drawing bisects the 30.0° angle. The magnitude of the force applied by each rope is 2900 newtons (N). (a) How much force would a single rope need to apply to accomplish the same effect as the two forces added together? (b) What angle would the single rope make relative to the dashed line?
illustrate a diagram to show the forces acting on the aircraft while it is flying in a horizontal circle with its wing banked at an angle to horizontal.
