A uniform 250 N ladder rests against a perfectly smooth wall, making a 35 degree angle with the wall. (a)Draw a free body diagram of the ladder. (b) Find the normal forces that the wall and the floor exert on the ladder. (c) What is the friction force on the ladder at the floor?

I have the free body diagram, just not sure how to continue..any help is appreciated

  • physics -

    write the following equations.

    sum of vertical forces=0
    sum of horizontal forces=0
    sum of moments about any point =0
    I recommend using the base of the ladder as the moment sum point.

    Those three equations will do it. Don't forget the weight of the ladder at the MIDDLE of the ladder.
