question number 4 please. 

Perform the following task. Stand so that you are facing a wall. Position your feet so that your toes are touching the wall where it meets the floor. While maintaining this position try to go up on your toes ("tiptoe" style). Describe what happens. Discuss rotation.

2. The planks shown below are all of the same mass and length. They are positioned on top of a wedge so that they are free to rotate. Rank the images below from largest to smallest torque generated by the plank's center of mass. Assume the largest is the one with the most "clockwise" torque, while the smallest is the most counter-clockwise. A Weight of board с Weight of board E 2022-06-10 Center of mass Center of mass Center of mass Weight of board B Weight of board ΔΔ D 3. In general, where is the center of mass located on the human body? Page 4 of 12 Center of mass Largest Torque Explain how you arrived at this ranking (include references to any appropriate physics equations) Center of mass Weight of board Smallest Torque 4. Perform the following task. Stand so that you are facing a wall. Position your feet so that your toes are touching the wall where meets the floor. While maintaining this position try to go up on your toes ("tip- toe" style). Describe what happens. Discuss rotation. 5. Repeat the above procedure away from the wall and (hopefully) success is achieved. What changed? Pay attention to how your body moves.
