What can you say about the nature of acceleration associated with a mass whose v-t graph is shown

Dear Student,  Slope of velocity time graph indicate acceleration of the body .

1- Because slope is constant for straight line hence acceleration of the body is constant and negative. 2- Because velocity decreases with time hence acceleration and velocity will be in opposite direction because velocity is positive hence acceleration is towards negative and never changes its direction.

3- So due to opposite acceleration body will stop after some time (t= 10s) and then i will move in the direction of acceleration.

Regards.
