Answer:
Los parámetros dados del movimiento son;
La velocidad con la que el atleta se dirige hacia la línea de salida = 6 m / s
El punto en el que se inicia el cronómetro = marca de 100 m
La ecuación para la distancia recorrida, 's', se da como sigue;
s = 6 m / s × t
La distancia total recorrida, d = 100 + s
∴ d = 100 + 6·t
