Two cables are attached to a bracket and exert forces as shown.
What are the magnitudes of the horizontal and vertical components of the resultant of the two
forces?
ANSWER: C
The Physics Behind
- Trigonometry i.e. sine and cosine functions are needed.
- For the 15.0 N,
- x-component is 15.0 cos(20.0°)
- y-component is 15.0 sin(20.0°)
- For the 6.00 N,
- x-component is 6.00 sin(40.0°)
- y-component is 6.00 cos(40.0°)
- The magnitude of the components of the resultant force can be determined by vector adding the corresponding components of each given force.
- The answer, therefore, is C.
