A bicyclist steadily speeds up from rest to 12.0m/s during a 4.40s time interval. Determine all unknowns and answer the following questions. What is the magnitude of the bicyclist's acceleration?

How far did the bicyclist travel during this time?

What belongs in the areas marked x and y? x: the internal energy of a piston system increases as heat is added and rises to a cool area y: as thermal energy is added to a container, some of the energy is lost to the environment x: as thermal energy is added to a container, some of the energy is lost to the environment y: the internal energy of a piston system increases as heat is added and rises to a cool area x: a cold spoon placed in hot liquid gets warmer y: thermal energy is converted to light energy x: thermal energy is converted to light energy y: a cold spoon placed in hot liquid gets warmer
