go into the first sprite and change g if you have any problems with the value i used assume no friction because hell yeah the animation stops just before 4kg weight hits the ground, thats why it seems weird cuz in reality 3kg weight would keep sliding for a while longer reference ball is just normal gravity- we do not ask questions about the reference ball (the 4kg weight falls slower than normal gravity for obvious reasons)
credit: i used maths from the initial position the thing to be derived was the acceleration of every block. doing so is fun. i like breathing
