$A$ force of $10 \ N$ is applied on an object of mass $2 \ kg$ over a distance of $1 \ m$. What will be the kinetic energy gained by the object in $J$?

$2$ particles of mass $1\,kg$ and $5\,kg$ have the same momentum. Calculate the ratio of their kinetic energies $(K.E.)$.

Two particles have masses in the ratio $1 : 2$. If they have the same kinetic energy, what is the ratio of their momenta?

Two bodies of masses $m_1$ and $m_2$ are moving with the same kinetic energy. If $P_1$ and $P_2$ are their respective momenta,the ratio $\frac{P_1}{P_2}$ is equal to:

$A$ ball is thrown vertically upwards with a velocity $v$ and an initial kinetic energy $E$. When it reaches half way to the top of its flight,what are its velocity and kinetic energy respectively?

If the momentum of a body increases by $0.01\%$,its kinetic energy will increase by ........... $\%$
