The kinetic energy of a body of mass $2 \ kg$ and momentum of $2 \ Ns$ is ............. $J$.

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

If the kinetic energy of a body increases by $0.1\%$,the percent increase of its momentum will be .............. $\%$

$A$ ball of mass $2\,kg$ and another of mass $4\,kg$ are dropped together from a $60\,ft$ tall building. After a fall of $30\,ft$ each towards the earth,their respective kinetic energies will be in the ratio of:

If the momentum of a body is increased by $100\%$,then the percentage increase in the kinetic energy is ............ $\%$

Four particles are given,all having the same momentum. Which one has the maximum kinetic energy?
