Question

A 20kg metal block is placed on a horizontal surface. The block just begins to slide when horizontal force of 100N is applied to it (a) calculate The coefficient of static friction (b) if the coefficient of kinetic friction is 0.4 then find minimum force to maintain it's uniform motion​

Answer 1

Step-by-step explanation:

I can't do the exercise a because you need the Fs to calculate the coefficient of static friction.
