AI Generated Solution

To solve the problem of finding the angle between two forces (5N and 2N) that results in different resultant vectors (17N, 7N, and 13N), we can use the formula for the magnitude of the resultant of two vectors: \[ R^2 = A^2 + B^2 + 2AB \cos \theta \] Where: - \( R \) is the magnitude of the resultant vector, ...
