In a warehouse, a large heavy crate of 1237kg needs to be lifted by an industrial crane. The student working in the warehouse found the 2 strongest slings available. Each sling has a safety rating of up to 1 metric tonne. This means that if the tension in the sling exceeds 1000kgg (where g is gravity on Earth's surface), the sling will break. Both slings are 1.5m long, each. The student needs to install hooks where the slings will attach to the crate. From the available positions, what is the furthest distance between the hooks allowable so that the slings will not snap when the crate is suspended by the crane?
