1. The problem statement, all variables and given/known data An object of mass m1 on a frictionless horizontal table is connected to an object of mass m2 through a very light pulley P1 and a light fixed pulley P2 as shown below. (a) If a1 and a2 are the accelerations of m1 and m2, respectively, what is the relation between these accelerations? (Use a_2 for a2, m_1 for m1, and m_2 for m2 as appropriate.) (b) Express the tensions in the strings in terms of g and the masses m1 and m2. (Use g, m_1 for m1, and m_2 for m2 as appropriate.) (c) Express the accelerations a1 and a2 in terms of g and the masses m1 and m2. (Use g, m_1 for m1, and m_2 for m2 as appropriate.) http://www.webassign.net/serpop/p4-38.gif 2. Relevant equations F=ma 3. The attempt at a solution First I know that Tension2 = 2Tension1 due to mechanical advantage. Therefore, Tension 1= m1a1 Tension 2= m2a2 if i substitute 2T1 into T2, i get 2m1a1=m2a2 => a1=m2a2/2m1 The web assign says it is wrong. Any ideas on how to set this up?
