Question

An object of mass m1 hangs from a string that passes over a very light fixed pulley P1 as shown in the figure below. The string connects to a second very light pulley P2. A second string passes around this pulley with one end attached to a wall and the other to an object of mass m2 on a frictionless, horizontal table.

(A) If a1 and a2 are the accelerations of m1 and m2, respectively, what is the relation between these accelerations? (Use any variable or symbol stated above as necessary.)

Find A2?

(B) Find expressions for the tensions in the strings in terms of the masses m1 and m2, and g.

Find T1? and T2?

(C) Find expressions for the accelerations a1 and a2 in terms of the masses m1 and m2, and g.

Find A1? and A2?

Explanation / Answer

Check out http://iweb.tntech.edu/murdock/books/v1chap4.pdf The last 3 and a half pages are this question all worked out. Careful though, the masses, accelerations, and tensions are oppositely (?) labeled. e.g. m1 for you is their m2 etc
