A horizontal force $F$ is exerted on a frictionless trolley as it moves through a distance $s$, and the trolley’s kinetic energy changes from $4.0\,\text{J}$ to $8.0\,\text{J}$. If the trolley is then acted on by a force of $2F$ across a distance of $2s$, what would the initial kinetic energy of $4.0\,\text{J}$ change to?
- A$16\,\text{J}$
- B$20\,\text{J}$
- C$32\,\text{J}$
- D$64\,\text{J}$
