Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

5) The bungee jumper, an 80-kg man, falls from the bridge at A with the bungee cord secured
to his ankles. He falls 20 m before the 17 m length of elastic bungee cord begins to stretch. The
3 m of rope above the elastic bungee cord has no appreciable stretch.
ANS.
3 m
The man is observed to drop a total of 44 m before being projected upward. Model the man as
a particle located at the end of the bungee cord. Neglect any energy loss and compute:
a) the stiffness k (N/m) of the bungee cord
b) the maximum velocity (m/s) of the man during his fall
c) the maximum acceleration (g's) of the man during his fall
a) k = 120 N/m
b) Vmax = 21.4 m/s
c) amax = 26.2 m/s^2 = 2.67 g's

A tugboat T having a mass of 19 Mg is tied to a barge B having a mass of 75 Mg. If the rope is "elastic" such that it has a stiffness of k=600kN/m, determine the maximum stretch in the rope during the initial towing. Originally both the tugboat and barge are moving in the same direction with speeds (vT)1= 15 km/h and (vB)1= 10 km/h, respectively. Neglect the resistance of the water.

12. Health Warning: This is a difficult question so proceed at your own risk. Just for fun, two 150-lb engineering students A and B intend to jump off the bridge from rest using an elastic cord (bungee cord) having a stiffness k = 80 lb/ft. They wish to just reach the surface of the river, when A, attached to the cord, lets go of B at the instant they touch the water. Determine the proper unstretched length of the cord to do the stunt, and calculate the maximum acceleration of student A. 120 ft VANSZÍSSZES
