Answer:

the impulse and change in momentum of the football is 18.83 N/s.

Explanation:

Given;

applied force, F = 420 N

time of force action, t = 22.3 s

The impulse and change in momentum of the football is calculated as;

J = ΔP = [tex]\frac{F}{t}[/tex]

where;

J is the impulse

ΔP is the change in momentum

J = ΔP = [tex]\frac{F}{t}= \frac{420}{22.3} = 18.83 \ N/s[/tex]

Therefore, the impulse and change in momentum of the football is 18.83 N/s.
