The velocity time curve of a moving poin...

The velocity time curve of a moving point is shown in Fig. Find the retardation of the particle for the porion `CD`.
.

A

`4 m s^(-2)`

B

`2 m s^(-2)`

C

`3 m s^(-2)`

D

`6 m s^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
B
The slope of the velocity-time graph represents acceleration or positive, it represents accelecration and if the slope is negatitve, positive, it represents acceleation and if the slope is negative, it represents retardation. The section `CD` of the graphe retesebts retardation and magnitude of retardtion is
`|vec a|=(Change in veloity)/(Time taken )=(60)/((70-40))=2 m s^(-2)`.
