@ MKh : ALL my documents are 2007 version , I suggest you download a converter (Google :Word document 2007 to 2003 converter and iA you'll be able to find what you want (: )

Yeah, that is right mesons are not baryons
...but a muon is not a hadron, it is a lepton :o that is what my textbook says and also wikipedia
Here: http://en.wikipedia.org/wiki/Lepton (check the leptop table)

You're right ..My bad (:
dk bose:
In Formula One racing, cars often take corners at speeds in excess of 50 m s-1, and
so there is a very real danger of skidding.
a)At a corner of radius 260m the track is banked at 20°. Calculate the maximum speed if no frictional force is required.
plzz anyone solve this question and give the solutions as fast as possible!!!!
dk bose:
The next part of the above question is also my doubt.the question is as follows-
(b)'Downforce' is used to keep a car in contact with the track. The motion through the air produces a force perpendicular to the direction of travel, pushing the car onto the track. A racing car of mass 720 kg takes an unbanked corner of radius 550 m at a speed of 50 m s-1. The maximum frictional force is 0.4 x (reaction from track).Calculate the downforce necessary to prevent the car from skidding outwards.
plzz solve this sum also and give the solutions as fast as possible!! itzzz urgent!!!!plzzz help me!!!

Anyone?
The answer is B but i dont get how :s
