Question

Please help me generate an angular acceleration curve for the knee from the data below and show work, Thanks! I can email excel data sheet

1. A bio mechanist studying the torque the knee experiences during a drop landing needs to know the angular acceleration profile during the task. Using a motion capture system the researcher can track the markers representing the hip, knee, and ankle joints. Your objective is to generate an angular acceleration curve for the knee from this data (posted along with this assignment) and find the peak flexion acceleration deceleration.

Explanation / Answer

Compute the data on excel, generate a graphic (dispersive x,y), then add a trendline (polinomic order 2) for each axis, whit the ecuation of the trendline take the coeficent of X^2, those will be the aceleration.
