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 velociyt is negative and decreasing. Now match the following two tales for the given `s-t` graph

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
For M, slope s-t graph is positive and increasing. Therefore, velocity of the particle is positive and increasing. Hence, it is A type motion. Similary, N,P and Q can be observed from the slope.
