Please see the explanation ...
Explanation:
This is an ill-posed problem. I see a whole lot of questions asking What is the impulse applied to an object at a given instant. You can talk about force applied at a given instant. But when we talk about Impulse, it is always defined for a time interval and not for an instant of time.
By Newton's Second Law,
Force:
Magnitude of the force :
Impulse :
