Task 7 F m A box with massm is affected by a constant force F with makes the angle a with a horizontal table (see the figure above). This force, in combination with the frictional force between the box and the surface, causes the box to move with a constant velocity v along the table. The frictional coefficient between the box and the surface is Mk- Decide the normal force N on the box from the surface expressed by the box's weight G, the frictional coefficient Ak. and the angle a. Choose one alternative: ON = mg 1+µk cos a ON = mg 1+sin a mg ON 1+Hg sin a O N = mg Hk cOs a O N= mg 1+µk tan a
