What is the kinetic energy of an object with a mass of $3 \ kg$ and a momentum of $2 \ Ns$?

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

$A$ $120\, g$ mass has a velocity $\vec v = 2\hat i + 5\hat j\, m/s$ at a certain instant. Its kinetic energy is .................. $J$.

Four particles $A, B, C, D$ of mass $\frac{m}{2}, m, 2m, 4m$ have the same momentum,respectively. The particle with maximum kinetic energy is:

$A$ particle is dropped from a height $h$. $A$ constant horizontal velocity $u$ is given to the particle. Taking $g$ to be constant everywhere, the kinetic energy $E$ of the particle with respect to time $t$ is correctly shown in:

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