Homework Help: 2 blocks, 2 pulleys

  1. Oct 11, 2007 #1
    A block of mass m_1 is attached to a massless, ideal string. This string wraps around a massless pulley and then wraps around a second pulley that is attached to a block of mass m_2 that is free to slide on a frictionless table. The string is firmly anchored to a wall and the whole system is frictionless.

    1.Given the magnitude a_1 of the acceleration of the block of mass m_1 , find a_2 , the magnitude of the horizontal acceleration of the block of mass.

    So I figured out that a_2=((m_1*g)-T)/m_1 ....

    2. Calculate a_1, the magnitude of the acceleration of the block mass m_1. Write an expression for a_1. Express the acceleration magnitude a_1 in terms of m_1, m_2, and g.
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
