If a metal, say tin is dragged on a surface having coefficient of friction as u, with a velocity of 60kph, then what will be the temperature generated due to friction at the surface of tin. I am in urgent need of this answer. it will be very kind of you if you send me this answer by Email. ravibhandari2006@gmail.com

Temperature is not easily defined, but is actually a measure of molecular activity, which is not very useful. Normally on a scientific basis temperature is discussed using the equality of temperature.

Actually there are some missing variables to answer the problem : the mass of the metal and its specific heat capacity.
I believe it could then be solved.

Also needed is the amount of time the tin is dragged. The longer its dragged the more work is done and the more heat generated.
