Problem 2

A person with mass m1 = 74 kg person climbs a distance d fromthe base of a uniform ladder before the ladder starts to slip. Theladder has a mass m2 = 30 kg and length L = 7.0 m and rests againsta smooth vertical wall at an angle θ = 65° with the floor. Thecoefficient of static friction between the floor and the ladder is0.40. Use the symbolic notations given before using numericalsubstitutions.

A) Find the normal force N from the floor and the force of thewall Fw on the ladder when the man is on the ladder.
