Question

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

A. -59.5 m/s2
B. -14.0 m/s2
C. -4.20 m/s2
D. -23.8 m/s2​

Answer 1

D. -23.8 m/s2​

Step-by-step explanation:

Answer 2

`\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).
