Determine the force of gravitational attraction between the earth (m = 5.98 x 10^24kg) and a 70 kg physics student if the student is standing at sea level, a distance of 6.40 x 10^6m from earth's center. do not round your answer at all.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
