    This is a multiple choice answer as classified in NCERT Exemplar

    (a, c, d) when we are calculating velocity of a displacement time graph we have to take slope similarly we have to take slope of velocity time graph to calculate acceleration . when slope is constant motion will be uniform.

    When we are representing motion by a graph it may be displacement time, velocity time or acceleration time. Hence B may represent time . for uniform motion velocity time graph should be a straight line parallel to time axis.

    if Quantity B may represent time. Also Quantity A is displacement if motion is uniform. Quantity A is velocity if motion is uniform

According to question, we can write

 10 = 1 2 a t 2 . . . . . . . . . . . . . . . ( 1 ) a n d                        

1 0 + x = 1 2 a ( 2 t ) 2 . . . . . . . . . . . . . . . . ( 2 )  

X = 1 2 A [ ( 2 t ) 2 t 2 ] = 3 ( 1 2 a t 2 ) = 3 0 m

Average speed = 4 v 2 3 v

= 4 v 3

(d) Initial velocity  = - v j ˆ

Final velocity = v i ˆ

Change in velocity  = v i ˆ - ( - v j ˆ )

= v ( i ˆ + j ˆ ) Momentum gain is along i ˆ + j ˆ

 Force experienced is along i ˆ + j ˆ

  Force experienced is in North-East direction.
