A woman with a mass of 55 kg is standing on a force plate. You record the vertical force acting on her body as she performs the following tasks: 1) she remains still for1 s, 2) she steadily squats down over the course of1 s, then 3) she holds the squatting position statically for1 s,4) steadily moves to an upright standing position over the course of1 s, then 5) remains in the standing position for1 s
.a. Draw one free body diagram showing the forces acting on the woman as she stands and moves on the force (using only clearly defined variables to describe the forces). (insert picture here)
b. Write the linear equation of motion (hint: use Newton's2nd Law) for this problem (using variables and there should only be 1 equation that represents all instances). Equation:
c. Draw a graph showing the vertical force that would be recorded by the force plate as the woman performs this maneuver (be sure to indicate some numerical values on the vertical and horizontal axes and their respective units). (insert picture here)
d. From your estimation of the vertical force, draw the corresponding Net Impulse of the recording (start at 0, only consider deviations above/below bodyweight, and indicate units). (insert picture here)
