Two crates connected by a rope of negligible mass lie on a horizontal surface. (See the figure.) Crate A has mass mA and crate B has mass mB. The coefficient of kinetic friction among each crate and the surface is k. The crates are pulled to the right at a constant velocity of 3.2 m/s by a horizontal force F
A) In terms of mA, mB, and k, Compute the magnitude of the force F?
B) In terms of mA, mB, and k, computes the tension in the rope connecting the blocks.
