Two bodies of masses $\displaystyle 1$ kg and $\displaystyle 4$ kg are connected to a vertical spring, as shown in the figure. The smaller mass executes simple harmonic motion of angular frequency $\displaystyle 25$ rad/s, and amplitude $\displaystyle 1.6$ cm while the bigger mass remains stationary on the ground. The maximum force exerted by the system on the floor is (take $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$ ).
Official answer
(3)
$\displaystyle 60$ N
