The coefficient of static friction between a concrete block and a surface is 0.8. The block weighs 20 lbf. If a horizontal force of 15 lbf is applied to the block, would the block move?
And if not, what is the magnitude of friction force? What should be the magnitude of the
horizontal force to set the block in motion?
