1. The problem statement, all variables and given/known data Three small children of mass, 20kg (first child),24kg(middle child) and 16kg (third child), respectively, hold hands and are pulled across a smooth frozen pond (which will occur sooner rather than later) by a larger boy on skates. He pulls thm via horizontal rope being held by the first child (20kg). The skater pulls on the rope with a force of 135N. Calculate each of the following : -the acceleration of the skater -the force with which each pair of children must hold hands to ensure that the chain is not broken. 2. Relevant equations Fnet=ma 3. The attempt at a solution I've solved the first part, which was 2.25, but for some reason i cant seem to get the right answer for the second part (90.0N, 36.0N). I've tried using Fnet=ma for the second part aswell, and haven't thought up anything else. I'm studying for a test, which is why I need to figure out how to do this, any help would be very much appreciated! Never mind! i figured it out!
