erica is learning to drive, so her dad took her to a large, empty parking lot where she can practice. erica slowly starts driving, accelerating until she reaches and maintains a good speed. halfway across the lot, she stops briefly to practice braking. then, she repeats the process: accelerating, finding a good constant speed, and slowly coming to a stop. which graph could show ericas speed over time?

Answer

Explanation:

Step1: Analizar el primer ciclo

Erica empieza en reposo, acelera hasta alcanzar una velocidad constante. Esto se representa por una curva ascendente seguida de una línea horizontal.

Step2: Analizar el frenado

Luego, ella frena y su velocidad disminuye a cero. Esto se muestra como una curva descendente hasta el eje del tiempo.

Step3: Analizar el segundo ciclo

Repite el proceso, por lo que se repite el patrón de curva ascendente, línea horizontal y curva descendente.

Answer:

La cuarta gráfica (la que muestra dos ciclos de aceleración, velocidad constante y frenado) es la correcta.
