One really long physics question

AP Phalen 1 Homework . Pulleya ii. In a well-organized paragraph, explain why each correct student is correct, and what is wrong with the wrong students' statements. (c) A student performs several experiments in which ropes of various langthe are released with various height differences. In each case, the student matoured the time required for one and of the rope to reach the pulley. After examining her data, the student decides that the time I might be given by the equation T - where y, is the initial difference in the heights of the two ands of the rope, and C is a constant with appropriate units. Another student examining the equation states that the equation fails to correctly model the motion of the rope. Give a reason why the equation fails to correctly give the time required for one and of the rope to reach the pulley.AP Phyalen ! Homework . Pulleya E. A benny rope is set over a small, ideal pulley so that one and is a distance y higher than the other, as shown in the diagram. The rope has total length I and a mass-to-length ratio of a(which would be measured in kilograms per meter). Suppose that the rope is roleroad from rest in this configuration. (2) Write expressions for the following in tamma of L, ], A and fundamental constants. i. The total mass of the rope ii. The mess of the piece of the rope of lengthy ili. The acceleration of the rope at the moment the rope is released, as a function ofy (b) Latv represent the speed of one and of the rope and a represent the magnitude of the acceleration of cme and of the rope. The rope is released at time r = 0 and the left and of the nope reaches the pulley at tamer = T. Three students examine the graph showm to the right and offer the following Sodom A: "That graph could represent the length y as a function of time." Sundem E: "That graph could represent the speed v as a function of time." Studiom C: "That graph could represent the socolecation a as a function of time." i. Which student(s) isare correct?
