Please answer with complete work

Bungee jumping is a kind of extremal sport. The bungee jumper jumps from a high bridge over a stream running in a deep canyon. He is tied to the bridge by a long elastic rope. As the jumper falls down, the rope stretches, and pulls the jumper up, so that he starts moving up after nearly reaching the water. In case the rope is too long (as a result of miscalculation), the jumper bumps into the water at high speed, with the risk bad consequences. Suppose the jumper jumps from the bridge over a canyon, and the height of the bridge over the bottom of the canyon is H =150m The length of the rope, L-100m . The elastic constant of the rope is k=100 N/m i.e. in order to extend the rope by / metres, we have to apply the force k./ Newtons. The jumper's mass is m=80kg The gravity constant is g-9.81 m/sec . The question is, whether the jumper will reach the bottom of the canyon, i.e. The water surface?? If not, how close he will approach the bottom
