(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Impulse is defined as: force x time

a) Find its unit expressed in term of the base units.

b) What quantity has the same unit?

What could it mean? (Impulse = change in momentum)

2. Relevant equations

I = F x T

P = mv

3. The attempt at a solution

a) First, we convert the force into its base unit, and then we solve.

I = F x T

= ML/T^2 x T = ML/T

b) L/T is v so

[F x T] = [mv]

[Impulse] = [Momentum]

Therefore, momentum has the same unit as impulse.

My problem is with the second part of question b. I know without the hint given in parenthesis that impulse and momentum are related, but what is it that they want me to explain? I found the question "What could it mean?" very vague, and I don't really know how I am supposed to answer it.
