Question
A uniform ladder 6.9 m long weighing 430 N rests
with one end on the ground and the other end
against a perfectly smooth vertical wall. The ladder
rises at 59.5 o above the horizontal floor. A 800 N
painter finds that she can climb 2.65 m up the
ladder, measured along its length, before it begins
to slip. Normal force exerted on ladder = 1230N
Part A: What force does the wall exert on the
ladder?
F=____N
Part B: Find the friction force that the floor exerts
on the ladder.
F=____N
