Question about linear momentum and angular

Click For Summary
SUMMARY

The discussion centers on the relationship between linear momentum and impulse in a rigid body with initial linear and angular momentum set to zero. It concludes that the vector sum of impulses and the final linear momentum will indeed be in the same direction, as derived from the equation L2 = I, where L denotes linear momentum and I represents linear impulse. Angular momentum is not relevant to this specific analysis, despite its mention in the context of rigid body motion involving both translation and rotation.

Homework Statement


If an analysis of momentum and impulse, a rigid body has initial linear and angular momentum zero, does this mean that the vector sum of the impulses and the vector of LINEAR momentum final, will be in the same direction?

Homework Equations


Systema moment 1 + System Extern Impulses (1-->2) = Sistem Momenta 2

The Attempt at a Solution


I supposed that, because they are vectors, right??
 
Physics news on Phys.org
If we let L denote the linear momentum and I the linear impulse (both vector quantities), then
L2 - L1 = I
This is a vector equation. If (for your problem) L1 = 0, then this reduces to
L2 = I
which says that both vectors must have the same direction.

Angular momentum is not involved at all here. Why did you mention it in the original question?

Ok, thank you! I was talking about angular momentum becasue it's included in an analysis for solve a problem where a rigid body is in translation and rotation.
