4. The carts collide. What diagram will show force that each car exerts on the other. Draw free body diagram. 5. Into which of the following quadrants would the analysis of the two air cart interaction be classified if the system was isolated and the kinetic energy was not conserved ?

Use the following information to answer questions 3 to 5. two air carts are pushed toward each other on a levelled air track as himrated below car track is an apparatus that uses a cushion of air to reduce friction so that the system; An air carts and air track can be modelled as an isolated system. myI = 0.500 kg my = 0.250 kg VII = 1.00 m/s VI = 0.50 m/s Cart II Cart I 3. The total momentum of the two air-cart system immediately before they collide is A. 0.63 N.S, + B. 0.63 N.S, - C. 0.38 N.S, D. 0.38 N.S
