A bullet of mass $\displaystyle 200$ g having initial kinetic energy $\displaystyle 90$ J is shot inside a long swimming pool as shown in the figure. If it's kinetic energy reduces to $\displaystyle 40$ J within $\displaystyle 1$ s , the minimum length of the pool, the bullet has to travel so that it completely comes to rest is
Official answer
(1)
$\displaystyle 45$ m
