The momentum of the blob of clay before collision which is the same as the initial momentum of the system is 8kgm/s.
Given the data in the question;
- Mass of the blob of clay; [tex]m_b = 1 kg[/tex]
- Velocity of the blob of clay; [tex]v_b = 8m/s[/tex]
- Mass of wood; [tex]m_w = 3kg[/tex]
Initial momentum of the system; [tex]P = \ ?[/tex]
Momentum
Momentum is simply the product of the mass of an object and its velocity.
Its is expressed as;
[tex]P = m * v[/tex]
Where m is the mass of the object and v is its velocity.
To determine the initial momentum which is the momentum of the blob of clay before collision, we substitute our given values into the expression above.
[tex]P = m * v\\\\P = 1kg * 8m/s\\\\P = 8kg.m/s[/tex]
Therefore, the momentum of the blob of clay before collision which is the same as the initial momentum of the system is 8kgm/s.
