Question

Please disregard the marks I’ve made in pencil I don’t think it’s right. Please show all work, I’m very confused on this worksheet. I’m especially confused on how you find the y axis values in degrees/second with the information given. Thank you!

1. Provided is sagittal plane knee movement pattern during the stance phase of running. Draw the knce angular velocity curve based on the knee figure Remember, to include the sign of the angular velocity (+ or- for each period you draw. (5 points) 35 30 so 75 100 Stance (%) 350 r 300 C 250 · 200 E 150 100 .50 -100 150 75 100 Stance(%) dentify the following time point(s). Mark the points with CAPITAL LETTERS on the graphs, as well as for the orresponding question. (5 points) D 2. Greatest positive angular displacement: 3. Angular velocity is zero: 4. Greatest positive angular velocity: 5. Greatest negative angular velocity:

Explanation / Answer

2). greatest positive angular displacement is :- is of 38 degree at 100% stance

3). angular velocity is zero at :- stance is 25% and displacement is 30 degree. & stance is 75% and displacement is 9 degree.

4). greatest angular velocity is when the slope of graph is positive when stance is 75-100%

and negative angular velocity is when slope is negative. when stance is 25 - 75 %
