Use the following for problems $23-26$

$$ During a game, Player A catches a pass while standing at rest. Before Player A can move, Player B$,$ whose mass

$$ is m $=150$ kg$,$ collides with Player A while running with an initial velocity of$$ v $=7\mathrm{.}00$ m$/$s$.$ Afterwards, the

$$ players$$ stick together and travel with a velocity of v $=3\mathrm{.}20$ m$/$s$.$ If the players$$ momentum is conserved,

$$ determine player B$\text{'}$s initial momentum.
