    1. The problem statement, all variables and given/known data

    A 5m uniform ladder weighing 120N is placed against a smooth wall in such a way that it makes 60 degrees angle w/ the horizontal. A man weighing 480N climbs up the ladder and stairs 1.5m from its upper end.

    a. Find the force exerted by the wall against the ladder. (N1)

    b.Find the horizontal and vertical components force exerted by the floor to the lower end of the ladder. (fx and fy)

    My answers:

    N1=228.63N
    fx=228.63
    fy=600n


    So, are my answers correct?


    any help will be appreciated, thank you
