So this is the time that the airliner on the rocket would switch on the engine. Okay, It follows a parabola and then at the lowest point turns on the engine. It maintains that the same height then for the rocket initially drops. Okay, I'm going to set the wife goes to zero line as the airliner as a line for the airliner. And then uh and then uh rocket initially it's also moving at constant velocity, because uh before it turns on the engine, Okay, and after my intention of the engine starts to accelerate, So yes, that's a move on. So the X line the airliner is moving at constant velocity, so it looks like this. Okay, so at the same time we can start to draw XT craft. Okay, so, so this is the flight path a of the rockets and the airliner. And then we also need to draw the XT graph for the emotions and the white graph uh for both for the motion of both objects as well. Okay, so this is the time that uh that the rocket needs to switch on the rocket engine. Okay, so this is what I've drawn, we're here shows the flight path. So um when we solve this problem, we went to uh draw a diagram that shows the flight paths. So that when the rockets um come up at the same height as the airliner, That's what these things off 1000 KM Between the two objects. Okay so let's move up like that about the airliner continue to move straight and we want to find at one time that their rockets. And sometimes it will uh it's uh it turns on its and jean then um and then it starts to move up. It was it drops the rocket and then undergoes projectile motion. And then um after a while uh drops the rocket, He tracked the rocket over here and the about the airliner is moving at the 150. The situation is about um and and I know which is flying horizontally. In the diagram and the graphs, indicate when the rocket is dropped, when the rocket motor turns on, and when the rocket climbs through the altitude of the airliner. Your answer should include (i) a diagram showing the flight paths of both the rocket and the airliner, labeled at several points with vectors for their velocities and accelerations (ii) an $x-t$ graph showing the motions of both the rocket and the airliner and (iii) a $y-t$ graph showing the motions of both the rocket and the airliner. Your job is to determine the minimum time that the rocket must fall before its engine starts. If your conclusion is incorrect what type of error did you make?
