At the end of the walk, what is the magnitude of the person’s resultant displacement measured from the starting point?
I found this answer to be 595.7697375 m after finding the vertical velocity to be -567.3170013 and the horizontal velocity to be -181.9148158.
The Attempt at a Solution
What is the direction (measured from due west, with counterclockwise positive) of the person’s resultant displacement?
For some reason, I just can not find the angle. I tried to do arctan(vertical velocity/horizontal velocity) which came out to be 72.22112883, but that answer won't work. I then tried -72.22112883 but that won't work either? What am I doing wrong? Please help!
