A baseball with mass 0.14 kilograms and speed 40 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.)

Question 2

A 4 kilogram block of ice is removed from a freezer where its temperature was maintained at 20 degrees Celsius. How much heat does the ice absorb as it is warmed to 10 degrees? (The specific heat capacity of ice is 2,000 joules per kilogram degree Celsius.)
