the question

6) A 8 kg object lies on a horizontal frictionless floor initially at rest. One force of 11 Newtons is applied to it in the +y direction (away from the floor), a force of 16 Newtons is applied to it in the -y direction (towards the floor), and another force of 20 Newtons is applied to it at an angle of 30 degrees above the +x direction. If these forces are applied to the mass for 1.7 seconds, what is the horizontal displacement of the mass
