Match Column-I with Column-II
 

	Column – I (x – t graphs)		Column – II (v – t graphs)
A.		I.
B.		II.
C.		III.
D.		IV.

	(A)	(B)	(C)	(D)
1)	II	IV	III	I
2)	I	II	III	IV
3)	II	III	IV	I
4)	I	III	IV	II

A. slope of x-t curve is increasing and positive and is zero at t=0. So, velocity is positive and increasing starting with zero.

B. slope of x-t curve is negative initially and have larger slope and it becomes zero ultimately at t=infinity. Hence, velocity is negative with larger magnitude, and it decreases with time and become zero after infinite time.

C. slope of x-t curve is constant and positive initially and then it is constant and negative later. So, initially velocity is positive constant and then at a instant its value become negative with constant magnitude.

D. slope of x-t curve is positive and constant. So, the velocity is constant and positive.
