Calculate the earth's gravity force on a 60 kg astronaut who is repairing the hubble space telescope 600 km above the earth's surface express your answer using two significant figures. 2.) compare this gravity force with his weight at the earth's surface. express your answer using two significant figures.

3.) in view of your result, explain why we say astronauts are weightless when they orbit the earth in a satellite such as a space shuttle. is it because the gravitational pull of the earth is negligibly small?

An ascending elevator, hanging from a cable, is coming to a stop. part a part complete identify all forces acting on the elevator from the list below. select all that apply. select all that apply. kinetic friction normal force tension weight static friction submitprevious answers correct part b draw a free-body diagram of the object. draw the vectors starting at the black dot. the location and orientation of the vectors will be graded. the exact length of your vectors will not be graded but the relative length of one to the other will be graded.
