The purpose of solving forces and balancing force with -43.6° is to determine the net force acting on an object when multiple forces are present, and to ensure that the object is in equilibrium (i.e. not accelerating).
2.To calculate the net force with a -43.6° angle, you will need to break down the forces into their horizontal and vertical components. Then, use trigonometric functions (such as sine and cosine) to find the magnitude and direction of each component. Finally, add all the horizontal components together and all the vertical components together to find the net force in both magnitude and direction.
3.A -43.6° angle signifies that the force is acting at an angle of 43.6° below the horizontal axis. This means that the force has both a horizontal and vertical component, and it is important to consider both components when calculating the net force.
4.An object is in equilibrium when the net force acting on it is zero. With a -43.6° angle, this means that the horizontal and vertical components of the forces must cancel each other out, resulting in a net force of zero. You can also check if an object is in equilibrium by ensuring that its acceleration is zero.
5.Yes, the angle of -43.6° can change in a force calculation if the direction of one or more forces changes. In this case, you will need to recalculate the horizontal and vertical components and then find the new net force with the updated angles. However, if the magnitude and direction of all the forces remain constant, then the angle of -43.6° will remain the same.
