Question 2

A 0.2-kg aluminum plate, initially at 20C, slides down a 10-m long surface, inclined at a 30 angle to the horizontal. The force of kinetic friction exactly balances the component of gravity down the plane so that the plate, once started, glides down at constant velocity. If 90 of the mechanical energy of the system is absorbed by the aluminum, what is its temperature increase at the bottom of the incline? (Specific heat for aluminum is 900 J/kg  C.)
 a. 0.16C
  c. 0.05C
  b. 0.07C
  d. 0.03C
