En un experimento de cinemática, un estudiante analiza el movimiento rectilíneo de un carrito sobre una pista horizontal. Durante la experiencia, registra la posición del carrito en distintos instantes de tiempo. Algunos de los datos obtenidos se presentan en la Tabla . A partir de la información proporcionada, construya los gráficos solicitados, determine las características del movimiento y responda las preguntas planteadas, justificando sus respuestas mediante el análisis de los datos experimentales.
