A block of mass 10 kg is placed on a horizontal frictionless surface. A smaller block of 5 kg is placed on the front of the block. The system is accelerated by a rope pulling on the larger block with a force of 200 N. The rope makes an angle of 30o above the horizontal. What is the minimum coefficient of static friction between the two blocks that will allow the smaller block to move with the larger block without sliding down?
