#2 Let us study in more details the orbit of Earth around the Sun. a) Knowing that the average distance between Earth and the Sun is exactly 1 AU, calculate the average orbital kinetic energy (K) of Earth with the equation (K) = ½ Mearth v². (here, you can obtain the value of v by making the approximation that the orbit is circular). b) Calculate the average gravitational potential energy (Ug) of the system Sun+Earth with the equation (Ug) =-G Msun Mearth / (note that, with this the general definition of Ug, the potential energy is negative and tends toward 0 when the objects are at infinity with respect to one another) c) Determine the value of the total energy of the system Sun+Earth. d) Determine the ratio (K)/(Ug) dital need
