Taking into account the gravitational pull of the sun, how much work is required

Question

Taking into account the gravitational pull of the sun, how much work is required to send a rocket ship of mass m from the surface of the earth to the surface of the sun? Additional Data: Mass of the sun = 1.99* 10^30 kg Radius of the sun = 6.95*10^8 m Distance from the earth to the sun = 1.49* 10^11 m Find the point between the earth and the sun where the pull of the earth's gravity matches that of the sun. Calculate the initial velocity of a cannonball fired from the surface of the earth if it is to land on the surface of the sun. Find the volume of the solid generated by revolving the region bounded by y = square root x, y = 0, and x = 16 about the line y = -3 using the disc method (cf. page 305 of the textbook); using the shell method (cf. page 314 of the textbook).
