A teeter-totter is 9 m long with a fulcrum placed 2 m from one end. A child sits on the shorter end, while another child sits on the longer end. What is the mechanical advantage/disadvantage of the child sitting on the shorter end? Draw and label all parts of the system.

A classmate is walking and has a ground-contact phase of 0.75 s with their right foot and a total cycle time of 1.30 s. Draw the different phases and calculate each phase's absolute and relative time.
