If you are floating in outer space, and you need to change your motion in order to get back to the safety of your spaceship. You throw your shoe away with a force of 320 Newtons, which means the shoe pushes back on you with a force of 320 Newtons. If you have a mass of 61 kg, what is the magnitude of your acceleration?
