Falling and Sliding Mass

  1. Jun 3, 2010 #1
    1. The problem statement, all variables and given/known data

    Mass m1=34.3 kg is on a horizontal surface, connected to mass m2= 5.30 kg by a light string as shown. The pulley has negligible mass and no friction. A force of 201.7 N acts on m1 at an angle of 32.1o.
    The coefficient of kinetic friction between m1 and the surface is 0.185. Determine the upward acceleration of m2.

    2. Relevant equations

    F_given * cos(theta) = F_Horizontal
    F_friction = mgμ_k
    F_horizontal - F_friction - T = m_1 * a
    T = m_2 * a + m_2 * 9.81

    3. The attempt at a solution
    F_horizontal - F_friction - m_2 * 9.81 = m_1 * a + m_2 * a
