Physics Question 50 – JEE-MAIN 2026

Two masses of $3.4\text{ kg}$ and $2.5\text{ kg}$ are accelerated from an initial speed of $5\text{ m/s}$ and $12\text{ m/s}$, respectively. The distances traversed by the masses in the $5^{\text{th}}$ second are $104\text{ m}$ and $129\text{ m}$, respectively. The ratio of their momenta after $10\text{ s}$ is $\frac{x}{8}$. The value of $x$ is ______.
