Si el grafico de velocidad vs tiempo muestra una gráfica horizontal, ¿Cuál(es) de las siguientes afirmaciones es(son) siempre correcta(s)? I. La rapidez del objeto es siempre cero
II. La aceleración del objeto es cero
III. La distancia recorrida es cero

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
