Atoy car moving with an average velocity of 0.55 m/s moves for a period of 6.2 seconds in a straight line. what was the displacement of the toy car?

3.41 meters

Explanation:

In order to calculate this you just need to multiply the average velocity by the time that the toy car was moving in that velocity and you will get the displacement, remember that displacement is the change in position from the initial point where the object started the movement, since in this case the car kept moving in opposite direction to the initial point:

Displacement:Velocity*time

Displacement: 0.55 m/s* 6.2 s

Displacement:0.55*6.2

Displacement: 3.41 meters.

With this we know that the toy car move 3.41 meters from its original position.

b is the correct
