1.	A bullet moving with a velocity of 230 m/s is stopped by a block of wood. Calculate the rise in temperature of the bullet assuming that all the heat generated is retained by the bullet. Specific heat capacity of lead = 126 J/kg/K.
Answer» Solution :`(1//2)MV ^(2) = mcd T, dT = V ^(2) //2c = (230) ^(2) //2 xx 126 = 209.9K`
