SUMMARY
The net force acting on the object in the provided diagram is calculated to be 32.8 N at an angle of 72° East. The calculation employs the cosine rule, specifically the formula c² = a² + b² - 2ab cos C, where the forces are 32.0 N and 38.0 N, and the angle between them is 55°. The final net force vector is expressed in terms of magnitude and direction, confirming the accuracy of the solution presented.
