what acceleration is required?

Question

Escape velocity is the speed required to break free of a body’s gravitational force. On Earth, escape velocity is roughly 14.7 km/s. What acceleration is required for a rocket to achieve that velocity in 3.5 minutes?

Answer 1

velocity = acc * time ... acc = Vel/time = 14700 m/s/(3.5*60)= 70 meters/sec², about 7.1 g
