One day while out on a space walk to repair your ship, you notice that you have forgotten to tie off your tether! You and the heavy wrench you are carrying are drifting slowly away from the ship with a velocity of V₁ = -1.53 m/s (this is negative since you are moving left in the figure). Your mass (including your suit) is M = 117 kg and you are carrying a wrench of mass m = 8.18 kg. You are one smart astronaut and and you throw the wrench in the direction away from your ship as hard as you can. The result is that afterward, your velocity is V₂ = 0.58 m/s (this is positive since you are now moving right in the figure).
