Consider two blocks connected as shown in (Figure 1). Block A has mass 2.00 kg, and block B has mass 5.00 kg. The table on which B sits is frictionless, the cord connecting the blocks is light and flexible, and the pulley is light and frictionless. The horizontal force F⃗ has magnitude F = 19.0 N, and block B moves to the left with an acceleration of 1.70 m/s2 . 1-What is the tension in the cord that connects the two blocks?

2-What is the coefficient of kinetic friction that one block exerts on the other?
