Answer:

0.012 s

Explanation:

Impulse is equal to change in momentum. Impulse is the product of force and time hence I=Ft and making t the subject of the formula then

[tex]t=\frac {I}{F}[/tex]

Substituting 910 for F and 11 kg.m/s for I then time of impulse will be

[tex]t=\frac {11}{910}=0.0120879120879120879120879120879120879120s\approx 0.012 s[/tex]

Therefore, the time is approximately 0.012 s
