Two crates connected by a rope of negligible mass lie on a horizontal surface. Create A has mass mA and crate has mB. The coefficient of kinetic friction between each crate and the surface is uk. The crates are pulled to the right at a constant velocity of 3.2 m/s by a horizontal forc F. Part A. In terms of mA, mB and uk calculate the magnitude of the force F. Part B In terms of mA, mB, uk, calcuate the tension in the rope connecting the block.
