Given:
The initial momentum is
[tex]p_i=100\text{ kg m/s}[/tex]The final momentum is
[tex]p_{f\text{ }}=0\text{ kg m/s}[/tex]The time duration is t = 2 s
To find the average force.
Explanation:
The average force can be calculated as
[tex]F\text{ =}\frac{|p_f-p_i|}{t}[/tex]On substituting the values, the average force will be
[tex]\begin{gathered} F=\text{ }\frac{|0-100|}{2} \\ =50\text{ N} \end{gathered}[/tex]Thus, the average force is 50 N
