Newton's Laws of Motion

  1. Oct 6, 2008 #1
    1. The problem statement, all variables and given/known data

    An airplane of mass 1.2 x 10^4 kg tows a glider of mass 0.6 x 10^4 kg. The airplane propellers provide a net forward thrust of 3.6 x 10^4. What is the gliders acceleration.

    2. Relevant equations

    F(net) = ma

    3. The attempt at a solution

    After drawing FBD's,

    F(net) = ma
    F = (m1 + m2)a
    a = F/(m1 + m2)
    = (3.6 x 10^4 N)/(1.2 x 10^4 kg + 0.6 x 10^4 kg)
    =2 m/s^2

    This seems way too easy, can anybody please help me?
