Let us call a motion, A when velocity is positive and increasing. A –1 when velocity is negative and increasing. R when velocity is positive and decreasing and R –1 when velocity is negative and decreasing. Now match the following two tables for the given s-t graph:
Column-I | Column-II |
(i) M | [A] A-1 |
(ii) N | [B] R-1 |
(iii) P | [C] A |
(iv) Q | [D] R |

Ans.
(i) [C]
(ii) [D]
(iii) [A]
(iv) [B]
Sol. In motion M: slope of s-t graph is positive and increasing. Therefore, velocity of the particle is positive and increasing. Hence, it is A type motion. Similarly, N, P and Q can be observed from the slope.
