An 80.0 kg hockey player collides head-on with a 65.0 kg hockey player. If the more massive player experiences a -3.50 m/s2 acceleration, what acceleration does the less massive player experience after the collision?

Use following information to answer parts a–c:
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.
