Using a rope, a child pulls a box across a rough floor at a constant speed. The tension in the rope is 105 N and the rope makes an angle of 37 degrees with the horizontal. Find the friction force acting on the box (due to the rough floor).

the rope is pulling, and lifting ...
forcelifting=105sin37
force pulling=105cos37
forcepulling-frictionforce=ma=zero
the problem is too easy...friction force=pulling force.
