Please log in or create a free account to view the full lesson or to leave a review, Build a Solar-Powered Car for the Junior Solar Sprint. The Physics Classroom has prepared an activity that steps students through both a conceptual and mathematical analysis of the motion. The reason it works is explained by the physical make-up of the rocket motors. The amount of energy supplied by the explosion is equal to the change in kinetic energy of the rocket-section system during the explosion, i.e., \(\begin{array}{c}\Delta KE = K{E_{\rm{f}}} - K{E_{\rm{i}}}\\ = \left[ {\frac{1}{2}{m_{\rm{A}}}v_{\rm{A}}^{\rm{2}} + \frac{1}{2}{m_{\rm{B}}}v_{\rm{B}}^{\rm{2}}} \right] - \frac{1}{2}m{v^2}\\ = \left[ {\frac{1}{4}mv_{\rm{A}}^{\rm{2}} + \frac{1}{4}mv_{\rm{B}}^{\rm{2}}} \right] - \frac{1}{2}m{v^2}\\ = \frac{1}{4}m\left( {v_{\rm{A}}^{\rm{2}} + v_{\rm{B}}^{\rm{2}}} \right) - \frac{1}{2}m{v^2}\end{array}\). When air escapes the balloon the balloon is propelled forward while the escaping air is forced backward, the friction on the straw also acts as a force opposite of the direction of travel of the balloon. This saves energy because the depleted first stage is not carried all the way into orbit, allowing the second stage to travel farther with less fuel. An internal explosion breaks an object, initially at rest, into two pieces, one of which has 1.5 times the mass of the other. Free and expert-verified textbook solutions. 1.7 Solving Problems in Physics. A rocket in its simplest form is a chamber enclosing a gas under pressure.
