Explanation:
Displacement is understood as the length and direction that a body travels to move from an initial point to an endpoint.
This displacement is represented with a vector or straight line that indicates the distance of the displacement and its length.
This displacement in an easier way to understand. It is the distance between the start point and the end point of the journey. Since the second point is equal to the first point, since Mary returns to the same place, there is no difference between the displacement.

Although the car takes the turn, but due to the inertia, the body will try to move forward; but since the seat belts are on, it is enforced to move with the car in a circular motion
First we know that the large truck would weight more so it's heavier. Heavier objects have more kinetic energy than lighter ones. The large truck would have more kinetic energy than the car.
