a 5 kg block is sliding on a horizontal surface while being pulled by a child using a rope attached to the center of the block. the rope exerts a constant force of 28.25 n at an angle of 30 degrees above the horizontal on the block. friction exists between the block and supporting surface (with 0.25 and 0.16 ). what is the horizontal acceleration of the block?
