1.Bsed on newton's 2nd law,predict what will happen to the spaceshutter's acceleration after a lift as it burns its fuel 2. Relevant equations F=ma 3. The attempt at a solution since fuel is being burnt, thus mass of space shutter is decreasing as fuel is being burnt. force is constant as it is determined by the gravitional force of earth on space shutter (correct me if im wrong,but constant i think). thus,acceleration will be increased in the space shutter. thx for feedbacks!
