A man pulls a 50.0-kg block of ice with a rope over his shoulder as shown below. Suppose that he applies just enough force to get the block moving and then he continues to apply the same force. If it takes 2.00 seconds for the block to move 3.00 meters and if the coefficient of kinetic friction between the block and the surface is ?? =0.100, determine the coefficient of static friction ?? between the block and the surface. You may assume that the acceleration of the block is constant.
