11.5 Friction - 1
A 20 kg metal
block is placed on horizontal surface. A block is just begin to slide when the
horizontal force of 100 N is applied to it. Calculate the coefficient of static
friction. If the coefficient of kinetic friction is 0.4, find the minimum force
to maintain its uniform motion.
