The $SI$ unit of momentum is
$\frac{{kg}}{m}$
$\frac{{kg.m}}{{\sec }}$
$\frac{{kg.{m^2}}}{{\sec }}$
$kg \times Newton$
The velocity of a particle depends upon the time $t$ according to the equation $v = \sqrt {ab} + bt + \frac{c}{{d + t}}$ The physical quantities which are represented by $a, b, c$ and $d$, are in the following order
The dimension of Planck constant equals to that of
