3-37. In a motion capture study of a runner, one frame shows the subject support- ing her weight on one leg, as shown in Fig. P3.37. The length of the foot seg- ment (from ankle to toe) is 8 in. and the length of the lower leg (from ankle to knee) is 18 in. Knee y in.

(a) Given the angles shown in Fig. P3.37(a), find the position of the knee if the runner's toes touch the ground at the point x = y = 0. (b) Now suppose that the same leg is positioned such that the knee is located in the second quadrant and oriented in the knee-down posi- tion (clockwise direction), as shown Fig. P3.37(b). If the knee is located at P(x, y) = (-6.25 in., 25 in.), determine the values of 0 and 02.
