A pitcher throws a 0.142 kgbaseball at 47.2 m/s. As it travels 16.8 mto home plate, the ball slows down to 42.5 m/sbecause of air resistance. Find the change in temperature of the air through which it passes. To find the greatest possible temperature change, you may make the following assumptions. Air has a molar specificheat of Cp
