Math Problem Statement
(24.1, 58.8) where all components are newtons. If a vectors direction is measured counterclockwise from the positive x-axis what angle in degrees 0-360 does the negative of that vector make
Solution
The problem asks for the direction of the negative of the given vector, which has components , with the direction measured counterclockwise from the positive -axis.
Step 1: Find the direction of the original vector
To find the angle for the original vector :
First, let's compute this tangent value:
Now, take the arctangent of this value to find the angle:
Let’s calculate that.
Thus, the direction of the original vector is approximately counterclockwise from the positive -axis.
Step 2: Find the direction of the negative of the vector
The negative of a vector points in the opposite direction of the original vector. To find the angle of the negative vector, we add to the original angle:
Thus, the angle of the negative vector is approximately 247.6°.
Final Answer:
The angle of the negative of the vector , measured counterclockwise from the positive -axis, is 247.6°.
