Question:
A major league pitcher throws a baseball with a speed of 162 kilometers per hour. If the baseball weighs 235 grams and its heat capacity is 1.7 J g−1 K−1, calculate the temperature rise of the ball when it is stopped by the catcher’s mitt. Assume no heat is transferred to the catcher’s mitt and that the catcher’s arm does not recoil when he or she catches the ball. Also assume that the kinetic energy of the ball is completely converted into thermal energy.
