Hal has a pet sink which has a mass of 10.0 kg. He likes it so much, he gave it a name, Eafin. While transporting the sink to his new apartment, Hal drops the sink of a balcony 5.00 meters above the ground. Luckily, Hal's sink, Eafin, lands on a padded spring which compresses it a distance of 25.0 cm. What is the constant for the spring that broke Eafin's fall?
