Two crates are connected by a rope lying on a horizontal surface (Figure 1). Crate A has mass mAmAm_A and crate B has mass mBmBm_B. The coefficient of kinetic friction between each crate and the surface is kkmu_k. The crates are pulled to the right at a constant velocity by a horizontal force FF.

In terms of mAmAm_A, mBmBm_B, and kkmu_k, calculate the magnitude of the force FF.

F=

This is not the answer mkg(mass A + mass B)

In terms of mAmAm_A, mBmBm_B, and kkmu_k, calculate the tension in the rope connecting the blocks. Include the free-body diagram or diagrams you used to determine each answer. Express your answer in terms of some or all of the variables mAmAm_A, mBmBm_B, kkmu_k, and acceleration due to gravity g.

T=

The answer is not mk(massA)g
