A 4.4 kg block located on a horizontal floor is pulled by a cord that exerts a force F = 10 N at an angle theta = 35 degrees above the horizontal, as shown. The floor has a coefficient of kinetic friction µk = 0.1. What is the magnitude of the acceleration [m/s2] of the block? What is the horizontal speed [m/s] of the block 4.4 seconds after it starts moving?
