Mr. N jumps off a bridge with a bungee cord tied around his ankles as shown. He falls for 15 m before the bungee cord begins to stretch. His mass is 75 kg and we can assume that the cord obeys Hooke's Law with a spring constant of 50 N/m. Neglecting air resistance and ignoring the mass of the cord, determine: a) How far below the bridge he will fall before coming to a stop (55.3 m) b) The height at which he reaches his maximum speed (25.6 m) c) The maximum speed he reaches (20.8 m/s) y=0 (b) $15 m ETOT 1 (c) 15m Ay=? ETOT 2 (a) Bungee jumper about to jump. (b) Bungee cord at its unstretched length. (c) Maximum stretch of cord. HINTS: a) compare the energy totals at the top and bottom to find Ay Mr. N jumps off a bridge with a bungee cord tied around his ankles as shown.
