AI Thread Summary
To calculate missile impact in kinematics problems, it's essential to analyze the velocities of both the F-14 and the MiG-28, along with the missile's acceleration. The F-14 travels at 509 km/hr while the MiG-28 moves at 592 km/hr, creating a separation distance of 848 m when the missile is fired. The missile accelerates at 135 m/s², and the calculations involve determining how far the MiG travels before the missile impacts, the distance between Maverick and the explosion, the time the missile is in the air, and its speed at impact. Participants in the discussion emphasize the importance of showing work to identify errors in calculations. Understanding these dynamics is crucial for solving the problem accurately.

Homework Statement




Maverick in an F-14 is moving at a constant velocity of 509 km/hr. He is chasing a "bogey," also known as a Russian MiG-28 (at least, in the movie they were - there's no such thing as a MiG-28), which is moving with a constant velocity of 592 km/hr in the same direction. Maverick can see that he's getting away, so he fires an air-to-air missile hanging from the wing of his aircraft when the separation distance is 848 m. The missile accelerates at 135 m/s2.

By the way, if you don't know what movie this is from, you deserve to be thrown in the gulag.
A. How far does the MiG travel before it explodes in a greasy Commie fireball?
B. How far from the explosion is Maverick?
C. How long was the missile in the air?
D. How fast was the missile going when it hit the MiG?

For some reason, I keep getting it wrong, and I have no idea why. Can someone help me with the answer? Can someone tell me the actual answer and then I can try to work to see how to get there?

Show what you've done so far. That way we can see where you are going wrong.
 
"greasy commie fireball"? Really? Actually, I kinda like the image (sorry to any of my commie friends). You need to post your work so we can see where you lost control. Can't post the answers either--rules (probably made by more commies).
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
