Answer 1

Answer:

I do no

?????????.......

Answer 2

Answer:

1. OA is a straight line graph between speed and time and it is sloping upward from 0 to A. Here, OA represents uniform acceleration.
2. OA is a straight line graph between speed and time and it is sloping upward from 0 to A. Here, OA represents uniform acceleration.AB is a straight line graph between speed and time which is parallel to the time axis (X-axis). So, AB represents uniform speed. There is no acceleration from A to B.
3. BC is a straight line graph between speed and time which is sloping downwards from B to C. Therefore, BC represents uniform retardation or negative acceleration.
