2.- Si una nave espacial se mueve de tal manera que en cierto momento comienza a desacelerar de tal manera que ha recorrido 1.5 X 10° Km hasta que su velocidad disminuyó en un 30 % gracias a que su desaceleración tuvo una
magnitud de 360 Km/ (h s). a) Determina que velocidad llevaba cuando comenzó a desacelerar (4 puntos); b) Calcula
el tiempo que requirió para llevar a cabo dicho cambio de velocidad (3 puntos).
