Linear Impulse-Momentum Principle - Conceptual Example 9.3-6

 

Consider that two bullets of equal mass have been fired with equal velocity toward a wooden block resting on a frictionless surface. One bullet is rubber and bounces off of the block, while the second bullet is made of steel and embeds in the block upon impact.

 

In which case does the block have the larger velocity following the impact?

 

rubber bullet
steel bullet
same velocity in both cases
