Two blocks, joined by a string, have masses of 6 and 9kg. They rest on frictionless horizontal surface. A 2nd string, attached only to the 9kg block, has a horizontal force = 30N applied to it. Both blocks accelerate. Find the tension in the string between the blocks.

    Both blocks accelerate at the same rate. Draw free body diagrams and write Newton's second law (F = ma) for each block. Solve for the two unknowns: accleration and string tension.
