Question :

Some "extreme sport fun loving person" wants to go bungee jumping. They're not sure if the cord is strong enough to stop them from hitting the ground, but decide to jump and try anyway. The bungee cord's "strength" is measured by its spring constant, which is 54 N/m. The person has a mass 80 kg. Here is a picture of how it all happens: (1) The person gets ready to jump from a platform 65 m from the ground. (2) After falling a distance of y1 = 20 m, the bungee cord begins to get tight. (3) The person is eventually stopped by the bungee cord, a distance y2 from the point where the cord began to get tight. Will the bungee cord stop the person before they hit the groundscreenshot tcdsb.elearningontario.ca 2020.08.03 13 38 05
