A. A particle is traveling without friction up and down hills and valleys. If its initial potential energy is 6 J and its initial kinetic energy is 78 J, what is its total energy, E?
E: J
B. If at a later point its potential energy is -14 J, what is its kinetic energy K at that point?
K: J
C. If at a still later point its kinetic energy is 61 J, what is its potential energy U at that point?
U: J
