Aman jumps off a bridge 80 metres above a river below. his feet are tied by a bungee rope that is 40 metres long when not stretched. at the bottom, his head just touches the water. use calculations based on energy to work out where he will finally come to rest when he stops bouncing. ignore the man's height.

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.
