Answer:
105.1N
Explanation:
According to the newton second law

Since the acceleration is zero, then;

Since;

Given the following
mass of ladder m = 14kg
acceleration due to gravity g = 9.8m/s²
θ = 50°
Substitute

Hence the magnitude of the friction force (in N) exerted on the ladder in the point of contact with the horizontal surface is 105.1N
