Two crates connected by a rope lie on a horizontal surface (see figure below). Crate A has mass mA and crate B has mass mB. The coefficient of kinetic friction between each crate and the surface is μk. The crates are pulled to the right at constant velocity by a horizontal force F. Calculate the magnitude of the force F in terms of mA, mB,& μk
