A basketball player shoots the ball, with the shoulder joint positioned at (13,17) and the elbow joint located at (50,63) on an x-y axis system, with units in cm.
a. Draw the x-y axis system, and label the coordinates and joint names.
b. Calculate the lenght of the arm segment.
c. Calculate the angle of the arm from the right horizontal (and draw it).
d. Calculate the x and y coordinates of the arm segment center of mass location, estimating that the segment center of mass is located at 43.6% of segment length relative to the shoulder.
e. Draw the location of the arm segment center of mass on your figure.
