The kinetic energy of a body of mass $4 \,kg$ and momentum $6 \,Ns$ will be (in $\,J$)

If a lighter body of mass $M_1$ and velocity $V_1$ and a heavy body of mass $M_2$ and velocity $V_2$ have the same kinetic energy,then:

Two bodies of mass $4 \,g$ and $25 \,g$ are moving with equal kinetic energies. The ratio of the magnitude of their linear momentum is:

$A$ particle of mass $m$ at rest is acted upon by a force $F$ for a time $t$. Its kinetic energy after an interval $t$ is

$A$ body of mass $2 \ kg$ is projected vertically upwards with a velocity of $2 \ m \ s^{-1}$. What will be its kinetic energy in $J$ just before it hits the ground?

$A$ 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?
