if the net work done on an object is positive, then the objects kinetic energy
decreases.
remains the same.
increases.
is zero.

Explanation:

The work - energy theorem states that the net work done on an object, $W_{net}$, is equal to the change in the object's kinetic energy, $\Delta KE$. The formula is $W_{net}=\Delta KE = KE_{final}-KE_{initial}$. If the net work done $W_{net}>0$, then $KE_{final}-KE_{initial}>0$, which means $KE_{final}>KE_{initial}$. So the object's kinetic energy increases.

Answer:

C. increases (assuming the options are labeled A: decreases, B: remains the same, C: increases, D: is zero)
