In the simulation above, the vehicle spends about 9.3 km/s of “delta-v” (the total change of velocity its engines can provide) to reach a speed of 7.8 km/s at 200 km. ni Ibura ry’umuvuduko: i Urufaya, Inzira% s Bya Hejuru Bya Hejuru.

Gushaka
Scroll the 3D launch slowly and watch the readouts. At what time does the speed pass 3 km/s, and what happens to the rocket at about that moment? Then find the moment the altitude stops rising while the speed keeps climbing.
