La posicion de un motociclista que se mueve en linea recta se representa en la siguiente grafica. En el intervalo de tiempo 3 s 7 s se puede afirmar que el motociclista tiene

Kinematics. Uniformly accelerated rectilinear motion. The position of the cyclist given in the graph is B) positive acceleration and is moving forward.

We discard option A) because if it were constant velocity, space x and time would advance at the same rate so that the graph would be a line. As in the interval 0 to 3s.

We discard C) because the speed is not negative, on the contrary it is increasing, that is, it is accelerating, so it is not D)

We conclude that it is B) is accelerating and advancing.

srry not in spanish hope this helps tho.
