Jack has a dream that he is stranded in the middle of a frozen pond. The ice is frictionless so he isn’t able to walk or push off of the ice to get back to shore. All he has is his backpack carrying his heavy physics textbook. a) Identify a pair of action and reaction forces that Jack could use to get back to shore. b) Explain how Jack could minimize the amount of time it takes for him to get to shore (consider Newton’s Second Law). c) Compare and contrast a rocket launch with Jack’s strategy to get back to shore. Use the principles of Newton’s Third Law in your answer.
