The Attempt at a Solution


I thought it was B but i don't have a key or any guide. This book was used and the answer written by the previous book user was C. Why?
 
Physics news on Phys.org
"Total energy" is "potential energy plus kinetic energy" so "b" is correct. I don't know of any quantity that is the ratio of energies.
