Homework Statement


A pendulum bob of mass 24.5 N is pulled aside by a horizontal rope. If the tension in the rope is 3.50 N, what's the angle between the pendulum and the vertical?


Homework Equations


Vectors


The Attempt at a Solution


tan^-1(3.50/24.5) = 8.13 degrees?

draw a free-body diagram

the rope pulling from the left, the weight down, and Tension at an angle to the upper right
 
it duznt seem like it is necessary
 
And it means the tension is the horizontal rope
