To see if this acceleration can be reached by the actual system, the engineers in the video conduct an experiment using a scale model of the glider system. in the scale model, they launch a piece of wood covered in fabric from a height of about 30 feet, using a bathtub full of water as the counterweight the result of this test shows that they did not reach the acceleration they had hoped for. now the engineers are faced with a problem: they must find a new way to launch the glider so that they can reach the desired speed and accelera- tion. they are forced to revise both the parameters of the experiment and their mathematical models. questions 3. is it possible for the bathtub to accelerate at 1.2g? explain why or why not. if it is not possible, how could you modify the system to generate this acceleration? 4. why would they use a scaled-down model to test their ideas? what are the benefits of this approach? what are the limitations of this model?
