6) A mass of 5 kg is at rest on a horizontal surface. One force is applied at an angle of 27 degrees below the horizontal (in the +x direction), and a force of 7 N is applied vertically upward (perpendicular and away from the surface). If after 3 seconds, it is moving at 10 m/s in the +x direction, what is the amount of force that was applied below the horizontal in Newtons?
