A block of weight `100N` lying on a horizontal surface just beging to when a horizontal to move when a horinzontal force of `25 N` acts on it Determine the coefficent of static friction

A 20 kg metal block is placed on a horizontal surface. The block just begins to slide when horizontal force of 100N is applied to it . Calculate the coefficient of static friction . If coefficient of kinetic friction is 0.4 then find minimum force to maintain its uniform motion.

A block of weight 200N is pulled along a rough horizontal surface at contant speed by a force of 100N acting at an angle 30^(@) above the horizontal. The coefficient of kinetic friction between the block and the surface is .

A body of weight 50 N placed on a horizontal surface is just moved by a force of 28.2 N. the frictional force and the narmal reaction are
