Question

The most critical conditions of launch performance are the result of some combination of high gross weight, altitude, temperature, and?

1) Unfavorable wind
2) Obstacles surrounding the launch site
3) Powerplant systems

Answer 1

Rocket acceleration depends on exhaust velocity, rate of mass ejection, and rocket mass.

Step-by-step explanation:

A rocket's acceleration depends on three major factors: exhaust velocity, rate of mass ejection, and rocket mass. The greater the exhaust velocity of the gases relative to the rocket, the greater the acceleration. The faster the rocket burns its fuel, the greater its acceleration. And the smaller the rocket's mass, the greater the acceleration. These factors are all important in determining the launch performance of a rocket.
