If the total translational kinetic energy of the molecules of oxygen in a container is 15 J at room temperature, what is the total rotational kinetic energy of these molecules?
 a. 5 J
 b. 10 J
  c. 20 J
  d. 25 J
  e. 0 J

Question 2

In braking an automobile, the friction between the brake drums and brake shoes converts the car's kinetic energy into heat. If a 1500-kg automobile traveling at 30 m/s brakes to a halt, how much does the temperature rise in each of the four 8.0-kg brake drums? (The specific heat of each iron brake drum is 448 J/kg/C).
