I need help!<br><br> Which statements best describe the motion of car A and car B?
pychu [463]

Answer : The correct options are :

2) car A and car B are moving in opposite direction.

3) car A is moving faster than the car B.

Explanation :

From the given position-time graph, we conclude that the car A shows positive slope and the car B shows negative slope. That means the object which has positive slope will move faster as compared to the object with negative slope.

In case of Car A, it is moving towards the positive direction of the position axis whereas Car B is moving towards the negative direction of the position axis which means that both cars are moving in opposite direction.

So, the car A is moving faster than the car B and both cars are moving in opposite direction.
