2. A 15 kg box sits atop a 25 kg box inside an elevator. If the elevator was accelerating downwards at 3 m/s?, how much force would you have to push the 25 kg box so that the 15 kg box falls off? Assume that there is no friction between the 25 kg box and the floor, and Us 0.6 between the 15 kg and 25 kg box.
