An object of mass m 1 hangs from a string that passes over a very light fixed pulley P 1 as shown in Figure P5.25. The string connects to a second very light pulley P 2 . A second string passes around this pulley with one end attached to a wall and the other to an object of mass m 2 on a frictionless, horizontal table. (a) If a 1 and a 2 are the accelerations of m 1 and m 2 , respectively, what is the relation between these accelerations? Find expressions for (b) the tensions in the strings and (c) the accelerations a 1 and a 2 in terms of the masses m 1 and m 2 and g . Figure P5.25
