Question:
See attached document. Same person and starts from rest. a.) For path A, calculate the final speed and the bottom of the mountain. Use kinematics and conservation energy to find final velocity. b.) For path B, do the same thing as for path A. c.) Find the initial potential and kinetic energy for paths A and B. Are they the same? d.) Find the final potential and kinetic energies for paths A and B. Are they the same? e.) Using the information from C and D, write the conservation of energy law for the changes in energies for this mountain. f.) Find the final velocity at the bottom of the mountain for path C. Is kinematics or energy conservation the better method? Why?
