Question

What is the acceleration of a 30 kg object when 180 N of a force is applied to it?

A) 6.0 m/s2
B) 60 m/s2
C) 210 m/s2
D) 5,400 m/s2

Answer 1

We must know that $F=ma$, where F is the force, m is the mass and a is the aceleration. Then:

$F=ma\Longrightarrow 180=30a\iff a=\dfrac{180}{30}\iff\boxed{a=6~m/s^2}\\\\\text{The answer is A.}$
