A bungee jumper with a mass of 41.0 kg is standing on a platform 66.6 m above a lake. The length of the unstretched bungee cord is 15.1 m. The bungee acts like an ideal spring when stretched with a spring constant of 150.0 N/m. If the bungee jumper falls off the bridge, determine her speed when she is 48.2 m above the lake. Ignore the effects of air friction. Enter a number with two significant digits
