You first walk 10 meters at an angle of 30 degrees East of North. Then, you walk 15 meters at an angle of 45 degrees South of East. Assume that East is +x and North is +y, and assume you started at the origin (0,0).   A. Make a graph with x- and y-axes and draw your path on that graph (to scale, or at least as close as you can get). Start the first vector at the origin, and the second vector at the tip of the first vector. Then, draw the resultant vector (their sum).   B. Break each part of the walk into their x- and y-components and then sum them to get the x- and y-components of the resultant vector. Make sure to include units and unit vectors.     C.

Question
You first walk 10 meters at an angle of 30 degrees East of North. Then,
you walk 15 meters at an angle of 45 degrees South of East. Assume that East is +x and North is
+y, and assume you started at the origin (0,0).
 
A. Make a graph with x- and y-axes and draw your path on that graph (to scale, or at least as
close as you can get). Start the first vector at the origin, and the second vector at the tip of
the first vector. Then, draw the resultant vector (their sum).
 
B. Break each part of the walk into their x- and y-components and then sum them to get the
x- and y-components of the resultant vector. Make sure to include units and unit vectors.
 
 
C. What is your displacement from where you originally started?
 
D. If the whole walk took 40 seconds, then what was your average velocity
