Recently, the Amazon and Virgin groups launched commercial space flights. These flights do not store fuel on board, instead, they inhale oxygen from the air. If the weight of one of these new rockets is 2420 kN, while a regular rocket is 19579 kN, what would be the acceleration of these two rockets close to the Earth's surface when a thrust of 25467 kN is applied?
