Answer:
[tex]32.6\ \text{kg m/s}[/tex]
Explanation:
[tex]p_f[/tex] = Final momentum of the system = [tex]32.6\ \text{kg m/s}[/tex]
According to the principle of conservation of angular momentum we have
[tex]p_i=p_f\\\Rightarrow p_i=32.6\ \text{kg m/s}[/tex]
The wall is not moving so the initial and final momentum of the system are equal.
So, the total momentum of the system before the collision is [tex]32.6\ \text{kg m/s}[/tex].
