Answer & Analysis
Answer
A
Analysis
To find the horizontal component of the
tension, you can use the formula:
where is the tension (90 N) and is the angle with respect to the vertical (25°). Since the angle is
given with respect to the vertical, we need to use for the
horizontal component.
Now, calculate:
