A car accelerates uniformly from rest and reaches a speed of 14.1 m/s in 10.9 s. The diameter of a tire is 26.6 cm. Find the number of revolutions the tire makes during this motion, assuming no sliping.
Answer in units of rev.

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
