# Can you integrate?

Let us name the block on the left as A and block on the right as B. Blocks A and B of mass $$m$$ are connected to a spring of spring constant $$k$$. If B is displaced left by distance $$x$$ and released at time $$t=0$$, Find the value of $\int_{0}^{∞}\text{N} \, dt$ Where $$N$$ is the normal force applied by the vertical wall. Give your answer in SI units.

Note: Take $$m=1 \text{ kg}, k=25 \text{ N/m}, x=70\text{ cm}$$. And assume all surfaces are smooth. Also assume the horizontal surface to be infinitely long .
