Find the direction of vector R counterclockwise of the + x axis

AI Thread Summary
To find the direction of vector R counterclockwise from the +x axis, the calculation involves using the arctangent function with the given components, resulting in an angle of 25 degrees. However, the correct answer is stated to be 181 degrees, indicating that the vector points in the negative x-axis direction. This discrepancy suggests a misunderstanding of the vector's orientation or the coordinate system used. Clarification is needed on whether additional factors influence the direction of vector R. Understanding the quadrant in which the vector lies is crucial for determining its correct angle.

Find the direction of vector R counterclockwise to the + x axis

Homework Equations





The Attempt at a Solution



This kind of threw me off balance. I know to get the direction of the vector R for the problem is arctan (5.07/10.87) which gives me 25.

However the answer is 181 degrees.

What am I doing wrong?

Thank you

So are you saying that R points in the negative x-axis direction?
Or are there more facts to this problem?
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
