Bonsoir tout le monde j aurais besoin d'aide Lors d'un contrôle technique, on étudie le freinage d'une voiture de poids P= 9,6 kN. La force de freinage totale (avant et arrière) mesurée vaut F= 8,92 kN. 1. Quelles sont les forces qui s'appliquent sur la voiture ? Les schématiser à l'échelle. 2. Donner les caractéristiques de la résultante des forces. 3. Calculer la variation de vitesse de la voiture en 1 seconde lors du freinage en m·s-1 puis en km·h-1.
