The A box is being pulled by a rope across a level floor as shown in
the diagram. The box is accelerating at 1 m/s2, the coefficient of
kinetic friction is 0.5. What is the tension in the rope?

1. The diagram is important. Is the rope horizontal? If it is, then
tension-friction=mass*acceleration
tension-mass*g*.5=mass*1
tension=mass(4.9+1)
So you need the mass....
