## Homework Statement

A 40.0-kg object is being pulled along a horizontal surface by means of a rope that exerts a force of 200 N at an angle of 30° below the horizontal. The coefficient of static friction between the object and the surface is 0.40. The force of friction on the object is:

A) 197 N

B) 173 N

C) 392 N

D) 157 N

## Homework Equations

µ_s = F_s/ F_n

## The Attempt at a Solution

So I got 197 N, which was A. However, the answer was B on the answer sheet. What have I done wrong?
