Question
Consider the collision between two blocks shown in the sequence of pictures below. Collision of Carts-Neglect friction between the table and the blocks a. Complete the free body diagrams for the blocks during the collision. Clearly label all forces. b. For each free body diagram you drew, how do the vertical forces compare in magnitude? Explain. Rank all horizontal forces in both free body diagrams. Explain your reasoning. c. During the collision, is the net force exerted on block A to the left, to the right, or zero? Explain how you can tell from your free body diagram. During the collision, is the net force exerted on block B to the left to the right, or zero? Explain how you can tell from your free body diagram. d. Newton's second law can be written as: F vector delta p vector /delta t. Using this form of Newton's second law allows for discussion of the change in the momentum of an object in terms of the net force exerted on that object. i. Is the momentum of block A conserved during the collision? Explain your answer. ii. Is the change in momentum of block A to the left, to the right, or zero? Explain your answer.Explanation / Answer
c)i since change in momentum of block A is in right direction so net force on A is in right direction
ii )since change in momentum of block B is in left direction so net force on B is in left direction
d)i) momentum of A is not conserved since initial momentum of A is 0 and finally it is not 0
ii) momentum change of A is in right direction
