Question

An object is struck by a 5N force for 8 seconds causing the object to experience a change in it's motion. What is the impulse acting on the object?

Answer 1

Hi there!

Recall the equation for impulse:

$I = \Delta p = F * t$

Where:

I = Impulse (Ns)

F = Force (N)

t = Time (s)

Plug in the given values:

I = 5 · 8 = 40 Ns
