A 1.04-kg binder is initially at rest on a wood desk. The binder is then pushed with a constant force of 4.2 N. Friction with a magnitude of 1.8 N is exerted on the moving binder by the surface of the desk. Draw an energy bar chart of the situation. Then determine the final velocity of the binder after it has been pushed 0.70 meters across the table.
