Chelsea needs to move a 30kg box which is stationary on a wooden floor; the coefficients of friction between the box and the floor are u, = .42 (for static friction) and uk = .31 (for kinetic friction). (a) Chelsea pushes the box exerting a force to the right. Draw a free body diagram repre- senting all of the forces on the box. (b) What is the maximum force with which Chelsea could push without causing the box to begin accelerating? (c) Suppose the box begins moving. With what force would Chelsea have to push it to keep it moving at a constant velocity?
