1 pts Question 3 rope block A5 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 28.39 N at an angle of 0 = 30 degrees above the horizontal on the block. Friction exists between the block and supporting surface (with fs = 0.21 and 4 = 0.15). What is the horizontal acceleration of the block? Question 4...
