When a rolling yo-yo falls to the bottom of its cord, what is its rotation as it climbs back up the cord? a. reversed rotation due to the rebound
b. reversed rotation due to inertia
c. same rotation due to the rebound
d. same rotation due to inertia

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
