Two trains $A$ and $B$ each of length $400 \,m$ are moving on two parallel tracks with a uniform speed $72\, km\, h^{-1}$ in the same direction with $A$ ahead of $B$. The driver of $B$ decides to overtake $A$ and accelerates by $1\, m \,s^{-2}$. If after $50\, s$, the guard of $B$ just brushes past $A$, what was the original distance between them ?

When an $A C$ source of voltage $V=V_{0} \sin 100 t$ is connected across a circuit, the phase difference between the voltage $V$ and current $I$ in the circuit is observed to be $\pi / 4$, as shown in figure. If the circuit consists possibly only of $R C$ or $R L$ or $L C$ in series, find possible values of two elements.
