Two rolling carts are moving toward each other at the same constant speed. Part A: Cart 1 travels to the right with a mass m1 = 0.2kg and while Cart 2 travels to the left with a mass m2 = 0.4kg. Assume the carts are traveling on a track. Draw a Force Diagram for Cart 1. How many forces are acting on Cart 1? How do you know? Use the proper naming convention when listing the forces here. Draw a Net Force Diagram for Cart 1. Describe in words how you draw the net force arrow on the diagram. How is this different from the way you draw your other arrows. Is the momentum of Cart 1 changing? Does this make sense with the direction of the net force? How do you know? (Hint - what is the definition of momentum. Are any of the quantities that make up momentum changing?) Part B: Cart 1 and Cart 2 collide. Consider the moment the two carts are in contact. Carts are still on a track. Draw a Force diagram for Cart 1 during the moment of contact in the collision. How many forces are acting on Cart 1? How do you know? Use the proper naming convention when listing the forces here. Draw a Net Force Diagram for Cart 1. Is the momentum of Cart 1 changing? Does this make sense with the direction of the net force? How do you know? (Hint - what is the definition of momentum. Are any of the quantities that make up momentum changing?)
