Question

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?

Answer 1

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

Step-by-step 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 =
`(F)/(t)`

where;

J is the impulse

ΔP is the change in momentum

J = ΔP =
`(F)/(t)= (420)/(22.3) = 18.83 \ N/s`

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