The kinetic energy of a body is increased by $4$ times. Its momentum will

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

Two masses of $1 \,g$ and $4 \,g$ are moving with equal kinetic energies. The ratio of the magnitudes of their linear momenta is

In the Olympic games,an athlete covers a distance of $100 \ m$ in $10 \ s$. The estimated range of their kinetic energy is:

If momentum of a body is increased by $20 \%$,then its kinetic energy increases by $....\%$

When kinetic energy of a body becomes $36$ times of its original value,the percentage increase in the momentum of the body will be : (in $\%$)
