Chapter 4, Problem 47P

(II) Redo Example 4–13 but (a) set up the equations so that the direction of the acceleration $\stackrel{\to }{a}$ of each object is in the direction of motion of that object. (In Example 4–13, we took $\stackrel{\to }{a}$ as positive upward for both masses.) (b) Solve the equations to obtain the same answers as in Example 4–13.
