$A$ light and a heavy body have equal kinetic energy. Which one has a greater momentum?

Express momentum in terms of mass and kinetic energy.

$A$ particle is released freely from a height $H$. At a certain height,its kinetic energy is two times its potential energy. Then,the height and the speed of the particle at that instant are respectively ($g=$ acceleration due to gravity).

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

If the kinetic energy of a body increases,then what happens to its momentum?

If the centripetal force acting on an object moving in a circle of radius $20 \, cm$ is $10 \, N$,what is its kinetic energy in $Joule$?
