- 1. You are standing perfectly still, and then you take a stepforward. Before the step your momentum was zero, but afterward you have some momentum. Is the principle ofconservation of momentum violated in this case? 2. Does the center of mass of a rocket in free space accelerate? Explain. Can the speed of a rocket exceed the exhaustspeed of the fuel? Explain. 3. Early in the twentieth century, Robert Goddard proposedsending a rocket to the moon. Critics objected that in avacuum, such as exists between the Earth and the Moon,the gases emitted by the rocket would have nothing topush against to propel the rocket. According to ScientificAmerican (January 1975), Goddard placed a gun in a vacuum and fired a blank cartridge from it. (A blank cartridge contains no bullet and fires only the wadding andthe hot gases produced by the burning gunpowder.)What happened when the gun was fired?III. Conservation of Momentum A.
