Given data
*The given force applied by the person is F = 20 N
*The given time is t = 2 seconds
The formula for the change in momentum of the cart is given as
[tex]\Delta p=F\times t[/tex]Substitute the known values in the above expression as
[tex]\begin{gathered} \Delta p=20\times2 \\ =40\text{ }\frac{kg.m}{s} \end{gathered}[/tex]Hence, the change in momentum of the shopping cart is 40 kg.m/s
