The space shuttle. During the first stage of its launch, a space shuttle goes from rest to 4973 $\mathrm{km} / \mathrm{h}$ while rising a vertical distance of 45 $\mathrm{km}$ . Assume constant acceleration and no variation in $g$ over this distance. (a) What is the acceleration of the shuttle? (b) If a 55.0 $\mathrm{kg}$ astronaut is standing on a scale inside the shuttle during this launch, how hard will the scale push on her? Start with a free-body diagram of the astronaut. (c) If this astronaut did not realize that the shuttle had left the launch pad, what would she think were her weight and mass?

things. This problem we need Teoh, find exploration of the shuttle given information that I've drawn here. We know these equation here ever in doubt concerning final velocity and distance. We know that's got 45 clubbers. You it has in Los de is 4000 and 73 Commerce power. So let's get started. So for a first we need to convert velocity two meters per second, sir. Velocity 4973 kilometers per hour. Well, that's really 4973 1000 meters. We divide that by 30. 600 will convert it from hours two seconds. We're gonna do that. Um, that gets me. I'm a cheat. Needs my answers from earlier, like 13 381.4 meters per second is what I had gotten right And then we're going to president or equation. Note that, um So the X is it was in 1381.4. The zero is equal to zero X is equal to 45 x not a sequel, A zero. So I have 1381.4 squared and I want to minus from it zero and then make this equal to two times X station X times who were careful 45 kilometers of drink. These meters is actually 45,000. Think about it. Made the mistake. I first saw this that was hung me up. So a X is equal to 1381.4 squared over 90 1000. And so from this we get the exploration of the eggs. I believe I got 21 point to look for a quick yapped. We would put two okay, 21.2 meters per second squared, but then calculated its we should get. That's our A that when you do or be B would be How hard to the scale push the Who? The Astra in the jet? Well, we have a person who, if you draw a free body diagram of the person the person is, um with the mass of 55 kilograms, I believe it was 55 school down, Did you? Okay, so we have 55. I was 9.8, forcing downward and then that's the That's our weight. But then we also have the thrust of the person times the acceleration of the rocket going the other direction, and this matters when you know what these two things are. So Teoh. 55 times nine 0.85 39 you and 55 times 21.2 11 66. So there's our Nunes knee upward and downward direction. So if you want toe with scale is pushing. Um, are the scale is pushing on the person with Yes, we said, How hard does the scale push on her eso There's this force and then there's her weight going down on her. But because of her weight going down, um, on this scale, where she's standing on this scale like so that means there's also the bonus dressed of the normal force to the scale. So the normal force from the person to the scale do normal I did in for Newton's is rise. Your mix of too many normals calls in at the normal force or actually raw. Does it in scale in s There we go because the scale is because there's a weight pulling down from the person to the scale. The scale is pushing back to the person with normal force of the same weight, so scale pushes with the total force of over 5 39 plus 11. 66 is so 666 696 similar. And five. I think you did it right and risk until check my notes. Yep. Again. All right now is one more thing to do in that C I wouldn't see. Say, what would she think? Her weight and mastery? Well, her weight. So if the person that didn't realize the answer the rocket went off the ground somehow she would think your weights to be 17 05 Newtons, cause that's the force skills pushing back honor. And so that's what the scale would read. Um, but And you think your master view, whatever. 17 05 Divided by 9.8 is so 173 basically 100 74 kilograms, 174 kilograms. So yeah, because the rocket is pushing up against her. There's these extra forces on the scale, so it's not just it's not just, um, her weight, but there's also the force of the rocket about being applied to the scale to the persons of pushing the scale down. It's that gets it so she thinks her weight is actually much more than would be and then gives you a much higher mass. Then she would think she has normally and we're done.
