[SOLVED] Kinetic Energy Question
An object is dropped off a cliff of height h and is subjected to an average force of air resistance of F. If the object has a mass of m the KE it gains during the fall will be equal to.
a. mgh
b. mgh + f
c. mgh -f
d. mgh+ fh
e. mgh - fh
What I'm not sure about is does air resistance even factor in KE which would then make it answe A or does it add or subtract to it.
