$A$ toy car of mass $100 \,g$ is moving with a velocity of $(\hat{i}+2 \hat{j}-3 \hat{k}) \,m/s$. The kinetic energy of the car is: (in $\,J$)

If the momentum increases by $0.01\%$,what is the percentage increase in kinetic energy (in $\%$)?

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:

$A$ graph between kinetic energy $K$ and momentum $P$ of a particle is plotted as shown in the figure. The mass of the moving particle is ........ $kg$.

If the linear momentum is increased by $5\%$,the kinetic energy will increase by.......$\%$

The kinetic energy of a light body and a heavy body is same. Which one of them has greater momentum?
