Consider the crates in Problem 12 (Fig. P4.12). Assume there is no friction between and the table. (a) Sketch all the forces on the crates. Include a coordinate system. (b) Determine the components of the forces along the coordinate axes. (c) Write Newton’s second law for motion along both coordinate directions. (d) Solve the equations from part (c) to find the acceleration of the crates and the tension in the string.
