Answer:
the final velocity of the two blobs after collision is 3.21 m/s.
Explanation:
Given;
mass of first blob, m₁ = 9 kg
mass of the second blob, m₂ = 5 kg
initial velocity of the first blob, u₁ = 5 m/s
initial velocity of the second blob, u₂ = 0
Let the final velocity of the two blobs after collision = v
Apply the principle of conservation linear momentum to determine v;
m₁u₁ + m₂u₂ = v(m₁ + m₂)
9 x 5 + 5 x 0 = v(9 + 5)
45 = 14v
v = 45 / 14
v = 3.21 m/s
Therefore, the final velocity of the two blobs after collision is 3.21 m/s.
