shank CM y (m)
1. Make a scatter plot of y-position versus x-position of the hip joint, knee joint, ankle joint, thigh CM, shank CM, and thigh-shank total CM using the data from Lab 1 (ie make an identical plot to the one you made in Lab 1 or just submit the one you already made if you completed it). The graph should be clearly labeled and easy to follow (use colors, a legend, and axes labels to help this). (2 pts) Show your answers in a table, as well as example calculations for the thigh CM, shank CM, and thigh-shank total CM. (3 pts) What movement do these kinematics appear to represent? (1 pt) Describe the change in knee angle over time (ie when is the knee flexing? when is the knee extending?). (1 pt) (2) Calculate horizontal velocity for the thigh CM and horizontal velocity for the shank CM using the data from the center of mass values you calculated in Part 1. Show your answers in a table, as well as example calculations for thigh CM and shank CM velocity horizontal. (2 pts) Initially during this movement, is the thigh or shank moving faster horizontally? At the end of this movement, is the thigh or shank moving faster horizontally? (1pt)
