Two identical masses m1 = m2 = m are connected by a massless spring with

spring constant k. Mass m1 is attached to a support by another massless spring with

spring constant 2k. The masses and springs lie along the horizontal x-axis on a smooth

surface. The masses and the support are allowed to move along the x-axis only. The

displacement of the support in the x-direction at time t is given by f (t) and is externally

controlled. Write down a system of diļ¬erential equations describing the evolution of the

displacements x1 and x2 of the masses from their equilibrium positions.

2. Relevant equations

3. The attempt at a solution

Is it: mx1'' = -k[x1-f(t)] + k[x2-x1-f(t)]

mx2" = -k[x2-x1-f(t)]

?

Thanks!
