This simple case of uniform staging enables us to calculate the ultimate rocket with an infinite number of stages. Sign up for free to discover our expert answers. Step Five: Whittle Down the Possibilities. But will physics prevent a full-scale version from succeeding? The rocket has two small engines. Materials needed for a balloon rocket include: multiple balloons, an air pump, scissors, straws, fishing line, tape, a cardboard tube, and binder clips. A classic "balloon rocket" project uses a single balloon taped to a straw and attached to a piece of string (Figure 1). SpinLaunch will cleverly attempt to reach space with minimal rocket fuel. This Interactive is intended for use at the middle to later stages of the learning cycle on kinematic graphing. v is the difference between final and initial velocity. Space is provided for students to show their work; it is essential that they do so since the answers can be found through the simulation without a calculation. (a) Assume a spherical asteroid has a mass of 3200 kg for each cubic meter of volume and moves toward the Earth at \(15\;{\rm{km/s}}\). The software consists of three parts; the first part is a GUI that enables the user to design a rocket. (We still need divide the calculation into stages--say, the burning of the first 4M, then the . a = v e m m t g, 8.78. where a is the acceleration of the rocket, v e is the exhaust velocity, m is the mass of the rocket, m is the mass of the ejected gas, and t is the time in which the gas is ejected. In this rocket simulation, a model rocket is launched from the ground.
