Problem

Blocks

A

(

2.0\,\text{kg}

) and

B

(

3.0\,\text{kg}

) are in contact on a frictionless horizontal surface. A constant horizontal force of

15\,\text{N}

is applied to block

A

toward block

B

. Taking the two blocks together as a single system, what is the magnitude of the system’s acceleration? a)

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

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

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

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