Answer:


\text{B. }-14.0\:\mathrm{m/s^2}

Step-by-step explanation:

From Newton's 2nd Law, we have
\Sigma F=ma.

Substituting given values, we get:


-35.0=2.50a,\\a=(-35.0)/(2.50),\\a=\boxed{-14.0\:\mathrm{m/s^2}}

*Note the negative sign simply implies that the mass is travelling downwards (direction).
