    tension in a string
    A 2.09 kg block is placed on top of a 10.9 kg
    block. A horizontal force of F = 63.3 N is
    applied to the 10.9 kg block, and the 2.09 kg
    block is tied to the wall. The coefficient of
    kinetic friction between all moving surfaces
    is 0.117. There is friction both between the
    masses and between the 10.9 kg block and the
    ground.
    The acceleration of gravity is 9.8 m/s2 .
    2.09 kg
    10.9 kg
    μ = 0.117
    μ = 0.117
    F
    T
    Determine the tension T in the string.
    Answer in units of N.
