A 70 kg stuntman jumps from building with a height of 15 m attached to a bungee cord. a. What is the potential energy of the stuntman at the roof of the building with respect to the ground?

b. What is the potential energy of the stuntman when he is 5 m above the ground?

c. If energy is conserved, in what form of energy is the rest of the energy?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.
