Relative Velocity of an aircraft carrier

AI Thread Summary
The discussion focuses on calculating the relative velocity of an aircraft carrier and a helicopter. The user is attempting to find the velocity of the carrier and the helicopter with respect to Earth to determine their relative velocity. They correctly express the equations for the velocities involved but seek confirmation on their calculations. The user provides specific values for the velocities and asks if their results are accurate. The conversation emphasizes the importance of expressing velocities in terms of the given vectors for clarity.

The Attempt at a Solution



Vch = Vce + Vhe Do I have this correct?

I am guessing I need to find the velocity of the carrier with the respect to earth, and also find the velocity of the helicopter with respect to earth. Than with these two answers I can find the velocity of the carrier with respect to the helicopter. Do I have this correctly?

You're on the right track.
Now try expressing \vec v_\mathrm{CE} and \vec v_\mathrm{HE} in terms of the given vectors.

By the way, your image is a bit large. Next time, can you make it a bit smaller (so it at least fits on a standard size screen) or upload it as attachment?
 
Here you go, I resized it. Sorry about that.

Ok so how does this look?

Vcw = Vce + Vwe which when numbers plugged in gives me 20 = Vce + 10. I ended up getting Vce = 17.3 m/h is that correct?

Vhe = Vha + Vae which when numbers plugged in gives me Vhe = 40 + 30. I ended up getting Vhe = 50 m/h am i correct or way off?

Thanks.
 

Thread 'Errors and significant figures'

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
