$p=3200 (kgm)/s$

Momentum, $vecp$ , is given by the product of an object's mass, $m$ , and velocity, $vecv$ .

$vecp=mvecv$

Given a mass of $400kg$ and a velocity of $8m/s$ ,

$p=(400kg)(8m/s)$

$=>p=3200(kgm)/s$

Note that momentum is a vector quantity, but we have no specified a direction. Our calculated value, therefore, is a magnitude.
