Task id10303
A box with a mass of 10 kg lies on a horizontal surface at some distance from a vertical wall, to which it is connected by a spring with a stiffness of 200 N/m. The coefficient of friction between the box and the surface is 0.2. The box is slowly moved 20 cm away from the wall, applying a horizontal force to it. What kind of work is done? In the initial position the spring is not deformed. g = 10 m/s2.
