A constant force acts on a block, driving it across a horizontal surface with no friction. Starting from rest, the block travels a fixed distance. What is the connection between the block’s final speed $v$ and its mass $m$?
- A$\sqrt{v} \propto \frac{1}{m}$
- B$v \propto \sqrt{m}$
- C$v \propto \frac{1}{\sqrt{m}}$
- D$\sqrt{v} \propto m$
