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.
