​Q11. Study the given graph and answer the following questions

         (i) Which part of the graph shows accelerated motion ?

        (ii) Which part of the graph shows retarded motion ?

        (iii) Calculate the distance travelled by the body in first 4 seconds of journey graphically.

                

Dear Student ,
Here in this case from the graph we get ,
(i) AB = Accelerated motion .
(ii) CD = Decelerated/ retarded motion .
(iii) Distance travelled by the body in first 4 seconds is ,
S=12×4×4=8 m
