What mathematical representation correctly identifies impulse

Answer 1

The mathematical representation that correctly identifies impulse is:

Impulse = change in momentum

Mathematically, impulse (J) is calculated as the product of force (F) and time (t), and can be expressed as:

J = F * t

where,
J = impulse (Ns or kg·m/s)
F = force (N)
t = time (s)
