Momentum has a magnitude and a direction.
Its magnitude is (mass) x (magnitude of the velocity)
Its direction is the same as the direction of the velocity.
The thing you should memorize is: Momentum = (mass) x (velocity). P=mv
The density of the block is mathematically given as

<h3>Density of block</h3>
Question Parameters:
50 cm by 100 cm by 200 cm has a mass of 8000 g.
Generally the equation for the density is mathematically given as

Where
v= 50 cm * 100 cm * 200 cm
v=1000000cm
v=10000m
Therefore

phi=8e-4
