Q. A 0.20 kg aluminium plate with an initial temperature of 20 degrees c slides down a 15.00m long surface that is inclined at 30 degrees to the horizontal. The force of kinetic friction exactly balances the component of gravity down the plane so that plate, once started, glides down at constant velocity. If 90 percent of the mechanical energy of the system is absorbed by the aluminium, what is the temperature increase of the plate while it is at the bottom of the incline? (c=9x10^2)
