Applied Maths Relative Velocity 2001 (b)

[CptNeutralize]

I'd like to ask a question about relative motion.

An aircraft carrier C is sailing at a speed of 12km/h relative to water. It spots a ship A 10km away on a bearing of N30°E. The velocity of A relative to water is 30km/h in the direction S30°E. The aircraft carrier C adjusts its course instantly so as to get as close to A as possible. Find the direction of the velocity of C relative to water.

A MILLION THANKS!

hu3, good, relative velocity is the toughest topic, what I've heard, almost all the students and even some teachers have complain about this topic and how tough it is.

@grandalf111 what are you talking about!!!!

i do applied maths and this is the easiest question in thw whole exam

look a full projectiles question and you will see the hard part of applied maths

a five year old can do relative velocity

@TheJimmenybillybob Yeah, Relative Velocity is blatantly easy, with the exception of two or three past questions.

Projectiles are easy too.

[TheJimmenybillybob]

@AkiThePirate the derivations in projectiles are hard if you dont learn them

[AkiThePirate]

@TheJimmenybillybob I found them quite obvious...

[TheJimmenybillybob]

@AkiThePirate your lucky then i always found it hard the fact that you wernt using actual numbers

[AkiThePirate]

@TheJimmenybillybob I hate using numbers.

Since I started applied maths, physics has been pissing me off with the ludicrous amounts of decimals.

[TheJimmenybillybob]

@AkiThePirate lol tell me about it sometimes you have to use them all too if you want accurate results. doing the specific latent heat capacity of everything messed with my head lol.

[AkiThePirate]

@TheJimmenybillybob I just dump them into my calculator in the right order.

@TheJimmenybillybob dude that is so not true i find relative velocity the hardest topic

[grandalf111]

@TheJimmenybillybob want to know why its hard for me? cause our teacher didnt teach us about this topic and expect us to know it by ourselves, oh and btw im only 15, so maybe its hard for my brain to receive and info at that time, maybe to you its easy :) but now its okay ^_^

[TheJimmenybillybob]

@grandalf111 i am sorry do you do applied maths? no then you dont know try and do some of the derivations in projectiles and talk to me when you know what you are talking about not just what youve heard

What school? i go to the institute of education.
