Chapter 5, Problem 28P

|| Two crates connected by a rope of negligible mass lie on a horizontal surface. (See Figure 5.54) Crate A has mass m_A and crate B has mass m_B. The coefficient of kinetic friction between each crate and the surface is μ_k The crates are pulled to the right at a constant velocity of 3.20 cm/s by a horizontal force $\stackrel{\to }{F}$ In terms of m_A. m_B, and μ_k, calculate (a) the magnitude of the force $\stackrel{\to }{F}$ and (b) the tension in the rope connecting the blocks. Include the free-body diagram or diagrams you used to determine each answer.
