The 539N was the Force with F=ma and a = g. I think I forgot to write that. The -428N was the Force with F=ma and a = 7.8m/s2. My inclination was to subtract the forces to get the force required by the bungee cord to slow the decent to the 7.8m/s2

Homework Statement A person weighing 55kg jumps off of a bridge with a bungee cord attached. The problem seeks to find the bungee cords Force vector when the acceleration is 7.8m/s2 in the downward direction. m = 55kg a1 = g = 9.8m/s2 To find: F1 when a2 = 7.8m/s2 downward. I've...
