1) An astronaut of mass 80kg is floating in deep space above a dwarf planet's surface with his feet toward the dwarf planet. He fires a thruster that provides a 290 N force horizontally (as if he were standing upright and horizontal would be coming out of his belly button). A small leak in his suit is projecting oxygen out of the front of his suit and downward at an angle of 20 below the horizontal. The oxygen leak provides a force of 40 N in the opposite direction of the leak (like a small rocket thruster). The dwarf planet provides a small gravitational pull downward with an acceleration of g = 2.2 m/s2
