Miss Atkins is on her first space walk. Her mass is 80.0 KG and she carries an empty oxygen tank with a mass of 10.0 KG. She throws the tank away from her self with the speed of 2.0 m/s. With what speed does she start to move off into space? Both the astronaut and the Tanger motionless before she throws the tank.

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
