Homework Help: Kinetic/Potential energy of spring mass system

  1. Dec 5, 2015 #1
    1. The problem statement, all variables and given/known data
    Question: Does the force F(t) acting on mass m1 affect the equations for kinetic and potential energy of the system?

    2. Relevant equations
    KE and PE (spring-mass system).png
    F(t) is known
    V(q) is potential energy | T(q) is kinetic energy
    3. The attempt at a solution
    I think PE is not affected.
    I think KE is affected, but not sure how???

    q1 is distance from wall to m1
    q2 is distance from wall to m2

    I am not clear what the question is but certainly, F(t() is an external force acting on the system.
