Which among the following is a form of energy?

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

Two masses of $1\,kg$ and $16\,kg$ are moving with equal kinetic energy. The ratio of the magnitude of their linear momentum is:

If the linear momentum is increased by $50\%$,the kinetic energy will increase by ............. $\%$

Two solids $A$ and $B$ of mass $1\, kg$ and $2\, kg$ respectively are moving with equal linear momentum. The ratio of their kinetic energies $(K.E.)_{A} : (K.E.)_{B}$ will be $\frac{A}{1},$ so the value of $A$ will be ..... .

Two bodies with kinetic energies in the ratio of $4 : 1$ are moving with equal linear momentum. The ratio of their masses is
