Problem 2: A body A of mass m = 1Kg and a body B of

mass M = 4Kg are interconnected by a spring as shown in
figure below. The body A performs free vertical harmonic
oscillation with amplitude a = 1.6 cm and frequency ω=
25/s. Neglecting the mass of spring, find the maximum and
minimum values of force that this system exerts on the
bearing surface.
