A plank is hung from the ceiling by a rope attached 3 meters from one end. The plank is 8 meters long. A 25 kg can of paint is placed 25 meters from the long end of the plank. Wanting to not spill the paint, where should you place a 55 kg sandbag so as not to tip the can? Assume the plank is massless.
