1.	The bob A of a pendulum released from 30^(@) to the vertical hits another bob B of the same mass at rest on a table as shown in Fig. 6.15. How high does the bob A rise after the collision ? Neglect the size of the bobs and assume the collision to be elastic.
Answer» SOLUTION :It TRANSFERS its ENTIRE momentum to the ball on the table, and does not RISE at all.
