HAHA :smile: So, its one of the top colleges out there... I've accepted the offer of admission. :approve:

Hi. How is the demand and the $$$$ prospects for a nuclear engineer?

(y2 -y1) ÷ (x2 -x1)?

Two ships P and Q are traveling at night with constant velocities. At midnight, P is at the point with position vector (20i + 10j) km relative to a fixed origin O. At the same time, Q is at the point with position vector (14i – 6j) km. Three hours later, P is at the point with position vector...

i heard that they also had strong aeronautical engineering programs.. any comments on that? but all in all... worth going there? (i.e. job prospects and degree value) :)

The rescue party moves at a horizontal speed of 5 km h-1. The leader of the party wants to give the walker and idea of how long it will take to for the rescue party to arrive. (b) Calculate how long it will take for the rescue party to reach the walker’s estimated position. --- i guess i have...

ah... so 6i+6j+2j = 6i+8j ?

Hi hootenanny.. i get what you've just said... and that was what i set out to do... but my markscheme has a diagram version i do not understand... i get the 2j and 6i lines above... but what have the done to the rest ? :confused:

:cry: I am not getting the answer...

A mountain rescue post O receives a distress call via a mobile phone from a walker who has broken a leg and cannot move. The walker says he is by a pipeline and he can also see a radio mast which he believes to be south-west of him. The pipeline is known to run north-south for a long distance...

Hey I have been offered admission to the Pennsylvania State University's College of Engineering... Do any of you have any idea about its reputation, degree value, grad. employment opportunities? etc. It would really help me out. Thanks :smile:

perhaps you guys know of any good web-sites or e-books that cover pre-calculus and calculus maths for newbies...?

ah.. i got it now.. the way I've done it now is; 3200a= 2320-1040-3200gx 1/20 ---- Is there any golden rule of thumb you can suggest me when working with these sort of questions? :)

that is exactly what i was thinking... solve the force horizontally and then vertically... however; that does not give me the answer that is in the mark scheme... 0.09 :confused:

Mechanics Question. IV :) A breakdown van of mass 2000 kg is towing a car of mass 1200 kg along a straight horizontal road. The two vehicles are joined by a tow bar which remains parallel to the road. The van and the car experience constant resistances to motion of magnitudes 800 N and 240 N...
