A double-stage, solid-propellant sounding rocket has the following properties: Stage n mo (kg) me (kg s-¹) Isp (S) 1 1.8 750 8 290 2 2.05 100 2 326 The rocket is launched into a vertical trajectory. There is a delay time of 3 seconds between burnout of the first stage and ignition of second stage. Neglecting aero-dynamical drag, the variation of air pressure with altitude and the variation of Earth's gravity with altitude, calculate the following: (c) Altitude and speed at first stage burnout. [2 mark] (d) Altitude and speed at the starting of ignition of the second stage. [2 mark] (e) Altitude and speed at the second stage burnout. [2 mark] (f) The maximum altitude achieved by the rocket.
