Suppose a spherical planet P has a uniform density of 4.96*10^3kg/m^3 and a radius R=1904 km. For a parcel that weighs 73 N on thesurface of the (spherical) earth, what is A) gp/ge and B) itsweight on the surface of P? Using the "tunnel mail" system what isC) the delivery time in seconds to the opposite side of P? and D)the maximum velocity of the parcel in the tunnel? E) What minimumvelocity must be given to the parcel to escape from the surface ofP? At an orbit radius of 4.96R, what would be the parcel's F)potential energy and G) total energy? H) How long in s would ittake the parcel to revolve about P in this orbit?
