| Type | Resultant of two forces (triangle/parallelogram law) |
| Difficulty | Moderate -0.8 This is a straightforward application of the cosine rule and sine rule to find a resultant force. It's a standard two-part mechanics question requiring only direct formula application with no problem-solving insight needed, making it easier than the average A-level question. |
| Spec | 3.03p Resultant forces: using vectors |
2 Two horizontal forces of magnitudes 12 N and 19 N act at a point. Given that the angle between the two forces is $60 ^ { \circ }$, calculate\\
(i) the magnitude of the resultant force,\\
(ii) the angle between the resultant and the 12 N force.
