Homework Help: physics

Posted by Anonymous on Sunday, November 4, 2012 at 9:49pm.

Bill the firefighter stands on an 8 meter ladder of weight 355 Newtons leaning against a smooth vertical wall. The ladder makes an angle of 50 degrees with the horizontal floor. The wall cannot provide any frictional force only a normal force. All frictional force acting on the ladder is provided by the ground and this has both a vertical and horizontal component associated with this ground force (the horizontal component is frictional, the vertical ground force can be thought of as a normal force. Bills weight is 875 Newtons and he has climbed 6.3 meters up the ladder (along the length of the ladder). Assume that the weight of the ladder acts at it's center.
