thanks thank you for the quick responce. I can not believe I missed I really hate it when I overlook the obvious. Thanks

I am having problem with two math questions that I have been asked to try and although I do not need to do them they are really frustrating me. First off intergrate (x-1)/squareroot(4x^2-1) I am sure this is something to do with replacing x to get cos^2 (x)-1 so that this becomes 2cos(2x)...

I do not know the answers to these, but making a guess... 1. mosquito's are generally found in warmer climates and so perhaps they are simply attracted to the heat source rather than you body 2. Perhaps this led them to realize that the O-zone layer reacts with UV soaking a certain proportion...

for the other question f=mgsin5-0.05*mgcos5 f=ma therefore you can work out the acceleration of the single truck then again use v^2=u^2+2as to work out the final speed then use conservation of momentum at the bottom i.e. mu=4mv and you can work out the final speed of all the cars

can you assume that the deceleration as he hits the ground is constant? If so use the formula v^2=u^2+2*a*s, This will let you work out the acceleration and so using F=ma you can work out his force. therefore 4^2/(2*0.2) =40 f=65*40=2600N This looks a bit big so I may be wrong

I am in the process of writing a report on the Physics of Jet engines and I have come across a problem I cannot comprehend. In the exhaust of many jet engines they allow the atmospheric air to mix with the air from the engine to reduce exhaust noise. From what I understand this allows the...

From what I understand the X-43 is not ment to be a shuttle replacement but rather to test their new scramjet propulsion system (I am just doing a project on this and I would appreciate it if you told me if this is correct or not). Also from what I understand the scramjet doesn't opperate...

a=(v2-u2)/2s

I am doing the advancing physics a-level (I did AS level last year). However, I didn't do any data analysis project we did a sensor project and a research and presentation project. Is your board OCR? Anyway if you need any help just message me and I will be happy to help.
