The jungle man carrying the dinner for his family has a total mass of 150 kg and from rest swings from the cliff by rigidly holding the tree vine, which is 12 m measured from the supporting limb A to his center of mass. Assume that the vine remains taut. Use A as the datum. A. What is the initial potential energy of the man? Consider the moment when the vine strikes the lower limb B. B. What is the kinetic energy at this instant? C. Determine his speed at this instant. D. Draw the FBD and EFD of the man just before and just after this instant. E. With what force must he hold on to the vine just before and just after this instant?
