Question 19 (8 points) Kara (55 kg) is standing next to her brother Ben (80 kg) on a large piece of frictionless ice. Being a bit of a joker, Kara decides to push her brother with a force of 200 N expecting him to slide across the ice while she remains standing in the middle of the ice rink laughing. (8 marks) a. Describe the motion that will actually be experienced by Kara and Ben. Imagine this scenario in your head first, then be sure to use appropriate vocabulary to describe the motion. Be sure to describe all parts of each person's motion: beginning, middle, and end. b. Apply your knowledge of Newton's Laws of Motion to explain why they undergo the motion described in part A. c. What is Ben's acceleration? What is Kara's acceleration? Are they the same or different? Calculate. Explain
