## Homework Statement

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 ??

## The Attempt at a Solution

300 Newtons - 100 Newtons = 200netowns

200 Newtons x Cos30 = 173 ?

is this the correct way to go about it ?
