If the coefficient of static friction is 0.350, and the same ladder makes a 64.0 angle with respect to the horizontal, how far along the length of the ladder can a 71.9-kg painter climb before the ladder begins to slip?
The same ladder is 46.7 Newtons in weight and 10.4 meters long.
I don't even know if you need all of the info. but if you could help me that would be amazing! Thank you... Have no idea where to start because I dont get the concept of torque.
