Answer:
- 3.33 m /s
Explanation:
m1 = 5 kg
m2 = 10 kg
u1 = 10 m/s
u2 = - 10 m/s
Let the velocity of the combination of the blob is v.
Use the conservation of momentum
[tex]m_{1}u_{1}+m_{2}u_{2}=\left ( m_{1}+m_{2} \right )v[/tex]
5 x 10 - 10 x 10 = (5 + 10)v
50 - 100 = 15 v
v = - 3.33 m /s
Thus, the velocity of the blob after sticking together is - 3.33 m/s.
