Un esquiador parte del reposo en lo alto de una colina que presenta una inclinación de 10.5 respecto a la horizontal. La ladera tiene 200m de largo y el coeficiente de fricción entre la nieve y los esquíes es de 0.0750. Al pie de la colina la nieve es horizontal y el coeficiente de fricción no cambia. ¿Qué distancia recorre el esquiador a lo largo de la parte horizontal de la nieve antes de detenerse?

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force
