A baseball with mass 0.14 kilograms and speed 48.1 m/s is caught. If all of its kinetic energy is converted to internal energy as it is caught, what is its temperature change? (Assume the baseball's specific heat capacity is 1,000 joules per kilogram degree Celsius.) Express your answer to two decimal places.
