(c) What will be the maximum height of each ball after the elastic collision? The mathematical analysis involves the calculations of slopes and areas for the two fuel stages and the free-fall stage that follows. Acceleration of the rocket is given as: a = v e m m t g. Acceleration depends on the exhaust velocity, burning of the fuel . When you inflate the balloon and then release its nozzle, air is expelled out the back of the balloon. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. This acceleration is depicted by the slope on the velocity-time graph. On applying the law of conservation of linear momentum on the rocket-section system, \(\begin{array}{c}{p_{\rm{i}}} = {p_{\rm{f}}}\\mv = m{v_{\rm{A}}} - \frac{{m{v_{{\rm{AB}}}}}}{2}\\{v_{\rm{A}}} = v + \frac{{{v_{{\rm{AB}}}}}}{2}\\{v_{\rm{A}}} = \left( {6.60 \times {{10}^3}\;{\rm{m/s}}} \right) + \frac{{\left( {2.80 \times {{10}^3}\;{\rm{m/s}}} \right)}}{2}\\ = 8.00 \times {10^3}\;{\rm{m/s}}\end{array}\).
