Below is a position-versus-time graph of an object. Letters A to E represent different segments of its motion. Using clear sentences, describe how this object move in the whole 19 s. In your description you must specify the starting position, the direction and magnitude of velocity for each segment, and the final position when the movement ends.

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.
