Question

All the graphs below are intended to represent the same motion. One of them does it incorrectly. Pick it up.

Answer 1

Correct option (b)
Explanation :

If velocity versus time graph is a straight line with negative slope, then acceleration is constant and negative.

With a negative  slope distance-time graph will be parabolic (s = ut - 1/2 at²)

So, option (b) will be incorrect.
