You are indeed a great teacher. I have search on how to solve relative velocity problems and still did not get the concept on the internet but you have made it easy for me to understand. Kudoos. Thank you very very very much.
Thank you so much for your brilliant work. I am a structural engineer in South Africa. I still reference you work to make sure I stay sharp. Your work is really special. Thank you again
Thank you congratulations on becoming a structural engineer. Yes, I constantly find myself wanting to learn new things or relearn the old topics to stay sharp in my profession as well. Great to have you on board.
Find the velocity relative to an inertial frame (in which the centre of the Earth is at rest) of a point on the Earth’s equator. An aircraft is flying above the equator at 1000 km h−1. Assuming that it flies straight and level (i.e., at a constant altitude above the surface) what is its velocity relative to the inertial frame (a) if it flies north, (b) if it flies west, and (c) if it flies east? please help with this
You have to calcualte the velocity of a point on the equation. v = d/t = 40,000 km / 86,400 sec (or 86160 sec if we take a side-real day). = 463 m/sec = 1,667 km/hour Then you add the vectors.
can I find V(resultant) by taking the square root of ((V plane)^2-(V in the x direction of the wind)^2, whole thing minus V in y direction of the wind? I am getting 61.55; what I solved incorrectly??
I appreciate your mathematics are correct and you’re obviously very good at what you do, but at the risk of being a bit a stick in the mud, in reality the pilot is probably just going to rise a bit in altitude, and keep the North on the compass pointed towards the tail, as then you have to be flying south ? At least that’s what I would do, I’m not a Pilot and I do realise that there is trade winds up high all the time due to convection and stuff, but maths don’t seem like a fix when calculations are fixed, but the rate of the wind is not, and can change within minutes…. There’s always one lol…. 😀
Our rudimentary physics problems do not always mirror the real world (nor were they intended to), but they are supposed to lay down the ground work in understanding and in how to solve problems. (For example most of our problems ignore wind resistance - which is off course very unrealistic in the real world.) But we need to learn how to walk first before we can run.
@@MichelvanBiezen I understand why mathematics are necessary in physics, I just think that maybe there is the tendency to get lost in maths at times when it’s reality we must deal with. Either way I appreciate the reply, and I enjoyed your video….
I definitely agree with that statement. When I was a student I always asked my professors for the relevance in the real world. We used to get lost in all the calculations and couldn't see how the equations meant something in the real world.
@@MichelvanBiezen There is never a danger of self delusion when you know the difference between an equation that does have a real world application, and an equation that doesn’t. The danger lies with people who can’t differentiate between the two, as I have personally dealt with a lot of people who can’t understand the difference, they argue that maths proves things, when maths only describes things, maths is a tool, and a very necessary one, but it won’t prove the natural cause to a natural effect, but if your an engineer then maths is invaluable.

thank you sir for everything all the way from south africa
Glad you found our videos. Welcome to the channel! 🙂
does square root of the tenor field of type (1,1) exist?
Please reply
Sir can you please make a video on metallicity calculation for star.. 🌟
Bro you're the goat
Thank you. Glad you like our videos.
Sir do you live in LA?
Yes, we live in a suburb of LA.
@@MichelvanBiezen awesome 😎 sir btw thanks for everything
how is the resultant speed y equal to vp MINUS vwy as im seeing its plus?
From the drawing you can see that Vr is smaller in magnitude than Vpy
Thanks for your help.
You're welcome!
Thank you for helping my homework🥹🙏🏻 i hope u will a great day
I just subscribed. ❤️
Thank you! 🍷

Hi sir. Your lecture touches my heart.......carry on
Thank you. We are glad you like it.
I need this! 👩✈️🛩️
Yes, this is an interesting problem
