Momentum of an object is calculated by multiplying the mass by the velocity.
p = mv
where:
p = momentum
m = mass
v = velocity
Let's take your given into account and put it in the equation:
p = mv
30,000 kg.m/s = (400kg)v
Velocity is our unknown, so to get it all we need to do is transfer mass (m) to the other side of the equation and isolate the velocity (v). When we do this, we need to use the opposite operation (rules of transposition).
(30,000kg.m/s)/(400kg) = v
Cancel out the kg and you are left with m/s.
75m/s = v
The answer is then D. 75 m/s.
Now for your second question, as you can see in the formula, mass and velocity is directly proportional to momentum. That means that the higher the mass or the velocity, the higher the momentum.
So if the velocity increases, the momentum increases as well.

Answer:
20.18 J
Explanation:
We are given that
Mass of bx=m=1.1 kg
Height=h=1.75 m
Initial speed of box=u=2.99 m/s
Final speed,v=2.56 m/s
We have to find the mechanical energy lost due to friction.
Energy at top=
J
Where 
At bottom,h'=0
Energy at bottom=
Energy lost=Energy(Top)-Energy(bottom)=23.78-3.6=20.18 J
