1. The problem statement, all variables and given/known data a boy uses a rope to pull a box weighing 300 Newtons across a surface with a constant velocity . The rope makes an angle of 30 degrees with the horizontal, and the tension in the rope is 100 Newtons. What is the coefficient of friction ?? 3. The attempt at a solution 300 newtons - 100 newtons = 200netowns 200 newtons x Cos30 = 173 ??? is this the correct way to go about it ???
