I'm working on my University Physics 1 homework and I need someone to coach me through the problems. I only have until 10/05/14 (Tomorrow at 11p.m.) and I need to get this done, but I have been struggling with what equations to use and how to solve it (The 2 books that came with the course do a poor job of telling me every equation that I need to know, so for the past month I have been trying to get help and figure the equations out on my own without being shown the proper steps to work the problems-- its gone rather unsuccessfully and only half the class is remaining this semester). Final edit: Please note that my College does not have a Physics tutor, as the only one available has transferred to UTD. I have been collaborating with the teacher and the students as best I can, but nothing seems to 'click'. 1. The problem statement, all variables and given/known data Two children on ice skates pull toward each other on a rope held taut between them. The inertia of one child is 34kg , and the inertia of the other is 26kg . 2. Relevant equations If at one instant the 34-kg child is accelerating at 1.3m/s2 to the left, what is the acceleration of the 26-kg child at that instant? Express your answer with the appropriate units. 3. The attempt at a solution For the solution, I thought that it would be an equation that only involved the inertia and acceleration of child 1 to somehow obtain the acceleration of child 2. But that is exactly where I'm getting stuck.
