NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A 210-kg electromagnet is at rest and is holding 100 kg of scrap steel when the current is turned off and the steel is dropped. The cable and the supporting crane have a total stiffness equivalent to a spring of constant 200 kN/m.
