Numerade a 62 kg bungee jumper jumps from a bridge. she is tied to a bungee cord whose unstretched length is 12 m. she falls a total of 31 m. (a) calculate the spring stiffness constant, k, of the bungee cord. assume hooke's law applies. (hint: consider the jumper at three different points – at the beginning of the fall, at a fall distance equivalent to the length of the unstretched bungee cord and at the bottom of the fall when the cord is at maximum stretch. what are the different potential and kinetic energies at each point? )

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
