Question

A tension of 35.0N is applied downward on a 2.50kg mass. What is the acceleration of the mass?

Answer 1

Answer:

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

Explanation:

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

Substituting given values, we get:

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

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

Answer 2

Answer:

D. -23.8 m/s2​
