You are floating in your space suit in deep space (no gravity), motionless relative to your single-person spaceship that is

100 m away. Your rocket pack is out of fuel and you have no tether, so you think at first that you are stranded forever. However, you are smart because you took Dr. Baird’s physics class. You take a 0.20 kg wrench from your belt and thrown it directly away from the spaceship at 18 m/s.

(a) If the mass of you and your space suit is 120 kg, how quickly do you move toward your space ship after throwing the wrench?

(b) How long does it take you to reach your ship?

    QUESTION 12 You find yourself stuck in outer space with nothing but your physics book and a space suit. You have a mass of 108 kg in your suit, and your physics book has a mass of 2.9 kg in order to make i back to your stationary spaceship before running out of air you must move at 0.10 m/s, How fast (in m/s) do you have to throw your physics book to achieve this speed?
