Angular Impulse-Momentum Principle - Conceptual Example 9.7-2

 

A bullet is fired horizontally with a velocity v_o into a box of sand hung by a piece of rope. The box of sand is initially at rest and the bullet embeds in the box.

 

 

Which of the following quantities are conserved during the impact of the bullet with the box if the system is considered to consist of both the bullet and the box?

 

energy
linear momentum
angular momentum with respect to O

 

 

 

Which of the following quantities are conserved, after the impact, as the box with embedded bullet swings upward?

 

energy
linear momentum
angular momentum with respect to O
