(III) Take the general case of an object of mass and velocity elastically striking a stationary object of mass head-on. ( ) Show that the final velocities and are given by

(b) What happens in the extreme case when is much smaller than Cite a common example of this.(c) What happens in the extreme case when is much larger than ? Cite a common example of this. What happens in the case when ? Cite a common example.

Solution 30P:

We have to derive the relation between the initial velocities of the two colliding bodies and their final velocities in terms of their masses.

Step 1 of 7

Concept:

Law of conservation of linear momentum: When no external force acts on the system, then the final momentum of the system is equal to their initial momentum.
