Derive equation of impulsive motion.

(Please also suggest a book to grasp impulsive motion)
Thanks

Are you given the equation and told to derive it, or are you simply trying to derive an equation, not knowing what it will turn out to be? If you have the equation, would you mind providing it?

I am familiar with impulse but not impulsive motion. It seems this could be an esoteric subject, or perhaps it is better known by some other term, since a Google search for impulsive motion reveals mostly published articles on specialized examples, rather than some general equation. (There is no Wikipedia article, no pages giving basic information that I could find.)

This is a past paper question. the complete question is here:

Q. What is impulsive motion? Derive its equation.

Exactly i am facing the same issue that you are facing.

Hmm, I've heard the words "motion" and "momentum" being interchangeable before. For example, I believe Newton's original wording of his second law uses the Latin word "motus" which can be translated "motion" but is interpreted to be "momentum." Maybe it's as simple as deriving I in terms of p as on this page? See also here.

Hope that helps.
