Uno de los ejercicios que los futbolistas suelen hacer para mejorar su velocidad es tratar de correr están atados a una banda elástica como se muestra en la imagen. Estas bandas por lo regular tienen una constante de restitución de 1750 N/m. Si un deportista de 80 Kg haciendo este entrenamiento lograr estirar la banda 0,1 m y el coeficiente de fricción entre los zapatos y el suelo es de 0,3 ¿Qué tanta fuerza debe hacer para mantenerse es esa posición?
