You stand on top of a skyscraper and drop a rubber ball from a height of 163 m. As the ball bounces off the floor it converts some of its energy into thermal energy -- it becomes warmer. Eventually, it stops bouncing and it has converted all the energy it initially had into thermal energy. How much has its temperature risen? (The specific heat of rubber is 2005 J/(kg*K).)
