Physics

A uniform ladder 5.30Â Â m long rests against africtionless, vertical wall with its lower end 3.10Â Â mfrom the wall. The ladder weighs 161Â Â N . The coefficientof static friction between the foot of the ladder and the ground is0.390. A painter weighing 741Â Â N climbs slowly up theladder.
a)What is the actual size of the frictional force when thepainter has climbed 1.0197Â Â m along the ladder?
b)How far along the ladder can the painter climb before theladder starts to slip?
completed part
What is the maximum frictional force that the ground can exerton the ladder at its lower end? 352N
