As part of a daring rescue attempt, the millennium eagle coasts between a pair of twin asteroids, as shown in the figure below where d1 = 2.55 km and d2 = 1.28 km. the mass of the spaceship is 2.53 x10^7 kg and the mass of each asteroid is 3.70x10^11 kg. find the speed of the millennium eagle at point a if its speed at point b is 0.990 m/s.

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.
