Thanks WTF_S;
To confirm, my contention is that the missile launches at a mass of 159,000 lbs, the majority of which is fuel, and all consumed within the initial, single, 5-minute, burn, which accelerates it on a high angle trajectory where y>x.
You contend that 159,000 lbs consisted of a, "majority of which is fuel," based on "what exactly?"
Total burn time = 5 minutes.
Any idea on the altitude and rate of travel achieved by the time of engine cut off? It is apparent you disagree with the 4500 km achieved at that time, contending an unpowered ballistic object can continue gaining a significant amount of altitude after impetus is removed.
Majority of the mass is fuel? It's an aluminium tube with a 2000lb warhead at one end, and a rocket motor at the other. You work it out. What exactly do you think is inside the part between the motor and warhead? Its a fuel tank or, for a solid fuel motor, containment for the fuel mass.
Altitude and velocity at engine shut-down? No idea, I'm not a rocket scientist. As a layman, I couldn't be more specific than to say its high and fast; not only has it been accelerating for the last 5 minutes, but its
rate of acceleration has been increasing as fuel is consumed. As an aircraft engineer, I know that its aerodynamic drag following engine shutdown will be very small-to-non-existent, due to the low-to-non-existent air density (drag being {drag-coefficient x air-density x surface-area x velocity-squared}/2). Therefore, the only braking force to its vertical velocity component is due to gravity.
Significant amount of altitude after impetus removed? You have maybe heard of the German Flak 36, the 88 mm anti aircraft gun from WW2? Its impetus was removed at an altitude of about 15 feet (the end of the barrel) and it had an effective altitude range of over 30,000 feet (around 6 miles), and that was in draggy-air.
