A toy car with charge moves on a frictionless horizontal plane surface under the influence of a uniform electric field Due to the force its velocity increases from to 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 to seconds are respectively
m/s, m/s
m/s, m/s
m/s,
To solve this problem, we need to analyze the motion of the toy car in two phases:Phase 1: From to second (initial acceleration)Phase 2: From
