A net force $F$ acts on an object of mass $m$ that is initially at rest. The object moves in a straight line. The variation of $F$ with the distance $s$ is shown.

What is the speed of the object at the distance $s_{1}$ ?

A. $\sqrt{\frac{F_{1} s_{1}}{2 m}}$

B. $\sqrt{\frac{F_{1} s_{1}}{m}}$

C. $\sqrt{\frac{2 F_{1} s_{1}}{m}}$

D. $\sqrt{\frac{4 F_{1} s_{1}}{m}}$
