(b) The acceleration of the knee in the X direction for frame 10.
(c) The angle of the thigh and leg in the spatial reference system for
frame 30.
(d) From (c) calculate the knee angle for frame 30.
(e) The absolute angular velocity of the leg for frame 30 (use angular
data, Table A.3).
(f) Using the tabulated vertical velocities of the toe, calculate its vertical
acceleration for frames 25 and 33.
6. From the filtered coordinate data in Table A.2, calculate the following
and check your answer from the results tabulated in Table A.3.
(a) The center of mass of the foot segment for frame 80.
(b) The velocity of the center of mass of the leg for frame 70. Give the
answer in both coordinate and polar form.
