Answer:

0.775 kg-m/s

Explanation:

Convert the units to the right unit forms necessary

250 g -> 0.25 kg

11.16 km/h -> 3.1 m/s

Now use the formula:

                         velocity

                   mass /  

momentum  /    /

       \           /    /

         \       /    /

          p = mv

p = 0.25 × 3.1 = 0.775 kg-m/s

Hope this helps you!

Bye!
