6. The force of a bungee cord varies roughly as F = 85 x, where 85 is the force constant of the cord measured in Nfrn and x = the distance the cord stretches from its unrstretched length measured in meters. a) Calculate the tension in the cord if it is stretched 20.0 m. b) A T63 kg bungee jumper falls while attached to this cord and causes it to stretch by 16.9 m. Calculate the instantaneous upward acceleration of the bungee jumper when the cord is stretched 16.9 m. T. A 37 kg kid jumps onto the ground from a height of2.6 111. She absorbs the shock of landing by decelerating for [1.41 5. Calculate the average force of the ground on the kid while she slows to a stop. You'll have to look up equations for freefall to solve this
