A ball is rolling down one hill and up another. Points A and B are at the same height on the two different hills . How do the velocity and acceleration change as the ball rolls from point A to point B?

Selecciona una de las siguientes respuestas posibles:

The velocity and acceleration are the same at both points.
The velocity and the magnitude of the acceleration are the same at both points, but the direction of the acceleration is opposite at B to the direction it had at A.
The horizontal component of the velocity is the same at points A and B, but the vertical component of the velocity has the same magnitude, but the opposite sign at B. The acceleration at points A and B are the same.
The vertical component of the velocity is the same at points A and B, but the horizontal component of the velocity has the same magnitude, but the opposite sign at B. The acceleration at points A and B has the same magnitude, but opposite direction.
