A toy car with charge q moves on a frictionless horizontal plane surface under the influence of a uniform electric field 
. Due to the force q 
, its velocity increases from 0 to 6 m/s in one second duration. At that instant the direction of the field is reversed. The car continues to move for two more seconds under the influence of this field. The average velocity and the average speed of the toy car between 0 to 3 seconds are respectively

t=0, v = 0 and t= 1, v = 6
6 = 0 + at
a = 6
Displacement for 1st second
Displacement for 2 nd second
=3
Displacement for 2 nd second
After 2 second the car will stop and starts moving backward
V=u+at
0=6-6t
t=1second
Displacement for 3 rd second
Total displacement=3+3-3=3m
Total distance=3+3+3=9m
