Problem 4.34

A body $A$ of mass $m_{1}=1.00 \mathrm{~kg}$ and a body $B$ of mass $m_{2}=$ $=4.10 \mathrm{~kg}$ are interconnected by a spring as shown in Fig. $4.9 .$ The body $A$ performs free vertical harmonic oscillations with amplitude $a=1.6 \mathrm{~cm}$ and frequency $\omega=25 \mathrm{~s}^{-1}$. Neglecting the mass of the spring, find the maximum and minimum values of force that this system exerts on the bearing surface.
