If the velocity of an object of mass $300 \ g$ is $(3\hat{i} + 4\hat{j}) \ m/s$,then its kinetic energy is . . . . . . $J$.

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

Two bodies of masses $m$ and $4m$ are moving with equal kinetic energy $(K.E.)$. The ratio of their linear momentums is

Two particles of masses $m_{1}$ and $m_{2}$ have equal kinetic energies. The ratio of their momentum is

Two bodies of masses $1 \ g$ and $9 \ g$ have equal kinetic energy. The ratio of their momenta is:

The masses of two substances are $4 \text{ g}$ and $9 \text{ g}$ respectively. If their kinetic energies are the same,then the ratio of their momenta will be
