3. Go Two horizontal forces, F, and F, are acting on a box, but only F, is shown in the drawing. F2 can point either to the right or to the left. The box moves only along the x axis. There is no friction between the box and the surface. Suppose that F, = +9.0 N and the mass of the box is 3.0 kg. Find the magnitude and direction of F, when the acceleration of the box is (a) +5.0 m/s², (b) – 5.0 m/s², and (c) 0 m/s².

1.A dockworker loading crates on a ship finds that a 225 kg crate, initially at rest on a horizontal surface, requires a 600 N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 550 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor. (a) the coefficient of static friction = and (b) the coefficient of kinetic friction = 2.
