A 4.3 kg block located on a horizontal floor is pulled by a cord that exerts a force F = 10.5 N at an angle theta 40 degrees above the horizontal, as shown. The floor has a coefficient of kinetic friction uk = 0.1. Determine the accelaration of the block in m/s: = Sum all forces in the horizontal direction: T1Rx + F1S = Fnet,y Then use Newton's Second Law: Fnet,y = m*aa. Submit Answer Incorrect.
