Capsule containing experiments Zero gravity is useful to carry out experiments on, for example, how liquids boil or ames form. However, going into space is very expensive. Afar cheaper approach is to use a drop tower- This involves dropping the experiment in a capsule in a tube inside a high tower. When it is in free-fall, inside the capsule is 132 m effectively zero gravity- This diagram shows a drop tower used by NASA. The capsule free-falls through 1 32 in until it meets the deceleration chamber which brings it to rest. The deceleration chamber is 6 m high and consists of polystyrene balls. The mass of capsule and experimental equipment Deceleration is usually 1130 kg. 6 m _l chamber a) How long is the capsule in free-fall? b) Calculate the deceleration produced by the polystyrene balls. Assume that it is constant over the 6 m of the deceleration chamber. c) Calculate the energy absorbed by the polystyrene balls by the time the capsule is at rest. d) In order to double the free-fall weightless time, it was planned to build a new drop tower. in addition, the new drop tower should have a deceleration chamber with a height so as to give half the deceleration. assumed constant. of the original. Calculate i) the free-fall height and ii the deceleration chamber hei ht needed to meet these conditions
