$A$ light and a heavy body have equal momenta. Which one has greater kinetic energy $(K.E.)$?

Two bodies of masses $2m$ and $m$ have their kinetic energies in the ratio $8 : 1$. What is the ratio of their momenta (in $:1$)?

$A$ 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 $.....m$.

An athlete in the Olympic games covers a distance of $100 \ m$ in $10 \ s$. His kinetic energy can be estimated to be in the range

$A$ light body of momentum $P_L$ and a heavy body of momentum $P_H$,both have the same kinetic energy,then:

If a light object (mass $M_1$ and velocity $V_1$) and a heavy object (mass $M_2$ and velocity $V_2$) have the same kinetic energy,then which of the following is true regarding their momenta ($P_1 = M_1 V_1$ and $P_2 = M_2 V_2$)?
