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?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
