Question: 4. (10 points) Two 131 students were discussing a problem in which the class was asked to nd the acceleration of a cart rolling up

4. (10 points) Two 131 students were discussing a problem in which the class was asked to nd the acceleration of a cart rolling up and down an incline at the instant the cart was at the very top of its path (not at the top of the incline). Homer says, \"At the top the velocity has to be zero so the acceleration has to be zero too.\" Marge disagrees saying, \"No, the velocity is changing at the top so the acceleration can't be zero.\" Who do you agree with? Discuss the reason for your answer and explain why the one who is wrong might legitimately be confused about which answer is correct. Note: This is an essay question. Your answer will be judged not solely on its correctness, but for its depth, coherence, and clarity
