Boris was tasked with developing a hypersonic rocket. He built two prototypes that were identical except that they have different gas velocities out of the nozzle. Which rocket was likely the slowest?
the rocket with highest gas velocity the rocket with lowest gas velocity
A B
The rocket goes upwards because the hot gases shoot downwards out of the nozzle. The faster the gases go downwards, the faster the rocket goes upwards.
