Step 1
Given mass of the ladder, m = 5 kg Acceleration due to gravity, g = 9.8 m/s^2 Weight, W = m * g W = 5 kg * 9.8 m/s^2 W = 49 N Show more…

The 15 m ladder has a uniform weight of 80 N. It rests against a smooth vertical wall at B and a horizontal floor at A. If the coefficient of static friction between the ladder and floor at A is 0.4, the frictional force acting at point A will be: a) 32 N b) 80 N c) 50 N d) 64 N

A 96.97 -kg person is halfway up a uniform ladder of length $3.433 \mathrm{~m}$ and mass 24.91 kg that is leaning against a wall. The angle between the ladder and the wall is $\theta=27.30^{\circ}$. Assume that the friction force between the ladder and the wall is zero. What is the minimum value of the coefficient of static friction between the ladder and the floor that will keep the ladder from slipping?
