A boy kicks a football with a force of 420.0 N for a time of 22.3 s. What is the impulse and change in momentum?

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 =

where;

J is the impulse

ΔP is the change in momentum

J = ΔP =

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