[killa0587]

1. George is going to bungee jump from a bridge that is 40.5 m over the river below. The bungee cord has an unstretched length of 27.5 m. To be safe, the bungee cord should stop George's fall when he is at least 2.00 m above the river. Ignoring air resistance, if George has a mass of 75.0 kg, what is the minimum spring constant of the bungee cord?
