The figure below shows two skaters and their masses. Let us refer to them as the left skater and the right skater. Initially they are stand still, facing each other. Assume there is no friction or air resistance in the problem. A) Calculate the normal force on the left skater. Show your work. B) Calculate the normal force on the right skater. Show your work. Now the two skaters push on each other. The left skater accelerations to the left at -0.65 m/s². C) Calculate the force in the x-direction acting on the left skater. Show your work or explain your answer. D) In what direction does the right skater move? E) Calculate the force in the x-direction acting on the right skater. Show your work or explain your answer. F) Calculate the acceleration in the x-direction acting on the right skater. Show your work or explain your answer.
