Imagine a 100-kg astronaut (including the space suit) is stranded in space with only a large bag (50 kg) of asteroid rocks (0.5 kg each). To get back to the exploration vehicle, she'll have to throw the rocks in one direction to move in the other. If she can throw 1 rock per second at a velocity of 30 m/s,- what is the specific impulse of her makeshift rocket?
- What is her thrust?
- What total ΔV can she generate?
