a bungee cord is attached to a wagon and is used to pull a child while you take her for a ride. the bungee's original unstretched length is 1.3 m. the
girl weighs 220 n, and the wagon weighs 75 n. you accelerate from rest to your normal walking speed of 1.5 m/s in 2 seconds, and you notice that
while you are accelerating, the bungee's length increases to about 2 m. what is the force constant of the bungee cord, assuming it obeys hooke's
law?
45 n/m
55 n/m
32 n/m
