Exam-style question
Try this first
A vector has a magnitude of 20 N and is directed 45° above the horizontal. Calculate the horizontal and vertical components of this vector.
Model answer
What a good answer should say
- The horizontal component is 14.14 N and the vertical component is 14.14 N.
Explanation
Why this works
This question assesses the understanding of vector resolution into perpendicular components. The formula used is: horizontal component = F * cos(θ) and vertical component = F * sin(θ).
The substitution and calculations yield the correct components.
