Question

A small rocket burns 0.0500 kg of fuel per second, ejecting it as a gas with a velocity relative to the rocket of magnitude 1600 m/s. (b) Would the rocket operate in outer space where there is no atmosphere? If so, how would you steer it? Could you brake it?

Accepted Answer

welcome back everybody. We are looking at a spaceship and I'm just gonna go ahead and draw our spaceship right here, something like that, give it a little bit of bottom funnel, give it a little wing out to the side. Now our spaceship is traveling in this direction, we're looking at it inside of an isolated system, so there's no matter around and we need to figure out how to change its direction and decelerate it far out in space. Well, I wanted to change its direction and it's it's already going forward. Here's what I would do. I would have a little tiny thruster on the side of the spaceship that when it fires would essentially result in this force pushing on the spaceship. So it's new resultant force would be maybe something out here that's maybe like it's new direction. Um but that's what I would do in order to change its direction to decelerate it. Well, if its current velocity is going upwards, I'm gonna have to push directly against it. Using some sort of thruster in the front. You're looking at this thruster which looks like a thruster in a sideways direction and looking at this thruster which is a forward facing thruster. This leads to our final answer choice of a thank you guys so much for watching. Hope this video helped. We will see you all in the next one
