A two-stage, solid-propellant sounding rocket has the following properties: First stage: mo= 249.5 kg, mf = 170.1 kg, me = 58.97 kg, me = 10.61 kg, slsp 4.053 kg, slsp = 235 s = 235 s Second stage: mo= 113.4 kg, mf = Delay time between burnout of first stage and ignition of second stage: 3 s. As a preliminary estimate, neglect drag and the variation of earth's gravity with altitude to calculate the maximum height reached by the second stage after burnout.
