This section contains SIX questions of matching type. The section contains TWO tables (each having 3 columns and 4 rows). Based on each table, there are THREE questions. Each question has FOUR options (A),(B),(C), and (D). ONL Y ONE of these four options is correct.
Answer questions Q. 8, Q. 9 and Q. 10 by appropriately matching the information given in the three columns of the following table.

A billiard ball, initially at rest, is given a sharp impulse by a cue. The cue is held horizontally a distance h above the central line as shown in adjacent figure. The ball leaves the cue with a speed V0
