Here is your answer,
a. motion indicated by O to A is accelerated motion while from A to B might be of rest.
b. After 10 second velocity is about of less than 20 m / s but more than 7 m/s .
Also at the 40 second the velocity is 0 means it came to rest then.
c. retardation can be calculated as by subtracting 20 -0and then dividing it by 10 seconds.
d. distance travelled between 10 th anf 30 th second is under the rectangle form by them perpendicularly on the axis.
