The final velocity of the block is 1.29 m/s
Explanation:
We can solve this problem by using the principle of conservation of momentum: in fact, the total momentum of the system must be conserved before and after the collision. Therefore, we can write:
where:
is the mass of the bullet
is the initial velocity of the bullet
is the final velocity of the bullet
is the mass of the block
is the initial velocity of the block
is the final velocity of the block
Re-arranging the equation and solving for v2, we find:

Answer:
<em>The volume of the feathers in ft³ = 16 ft³</em>
Explanation:
Density: This can be defined as the ratio of mass of a body to the corresponding volume of that body. The S.I unit of Density is kg/m³
Mathematically it can be expressed as,
D = m/v ................................... Equation 1
making v the subject of the equation above,
v = m/D ............................. Equation 2
Where D = Density of the feathers, m = mass of the feathers, v = volume of the feathers.
Given: D = 0.50 lbs/ft³, m = 8.0 lbs.
Substituting into equation 2
v = 8/0.5
v = 16 ft³
<em>Thus the volume of the feathers in ft³ = 16 ft³</em>
