Do action and reaction pairs result in equilibrium?

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?
