Bungee-cord jump. A 61.0 kg bungee-cord jumper is on a bridge 45.0 m above a river. In its relaxed state, the elastic bungee cord has length \( L = 25.0 \text{ m} \). Assume that the cord obeys Hookeβs law, with a spring constant of \( 160 \text{ N/m} \). (a) If the jumper stops before reaching the water, what is the height \( h \) of her feet above the water at her lowest point? (b) What is the net force on her at her lowest points (in particular, is it zero)?
