Taking into account the definition of density, the volume of the metal block is 3 m³.
<h3>What is density</h3>Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
<h3>Volume of the metal block</h3>In this case, you know that:
- Density= 5000
- Mass= 15000 kg
- Volume= ?
Replacing in the definition of density:
Solving:
volume×5000 = 15000 kg
volume=
<u><em>volume= 3 m³</em></u>
In summary, the volume of the metal block is 3 m³.

Hi there!
This is an example of a recoil collision.
Using the conservation of momentum:
The initial momentum is 0 kgm/s (objects start from rest), so:
We are given that the 15 kg block has a velocity of 12 m/s to the left, so:
Solve for v2':
