11. Early one morning, Tyrone went on a bicycle ride. His bike’s headlight
generator turned on as he pedaled. Tyrone used 2000 J of chemical energy to
pedal the bike: 1250 J was converted to the kinetic energy of Tyrone and the
bike, and 100 J was converted to thermal energy through various other energy
conversions. Describe two other ways energy was converted from one form to
another as Tyrone rode his bike. How much energy was present in those
conversions? Explain your answer.

12. On a swing, Kimi has an initial maximum potential energy of 300 J. As Kimi
swings between her highest and lowest points, 5 J is converted to thermal
energy. No other energy transformations occur. For two full swing cycles,
create a table showing the maximum kinetic energy, maximum potential
energy, the thermal energy, and the total energy of the swing.
