Problem

A constant horizontal net force of

12\,\text N

causes a crate of mass

6\,\text{kg}

to accelerate at

2.0\,\text{m}\!\cdot\!\text{s}^{-2}

. Under the same net force, what is the magnitude of the acceleration of an identical crate whose mass is

4\,\text{kg}

? (a)

2.0\,\text{m}\!\cdot\!\text{s}^{-2}

(b)

4.5\,\text{m}\!\cdot\!\text{s}^{-2}

(c)

3.0\,\text{m}\!\cdot\!\text{s}^{-2}

(d)

1.5\,\text{m}\!\cdot\!\text{s}^{-2}
