Problem

Blocks A (

2.0\,\text{kg}

) and B (

3.0\,\text{kg}

) are placed in contact on a horizontal surface that can be considered frictionless. A constant horizontal force of

10\,\text{N}

is applied to block A, pushing it toward block B so that the blocks move together. What is the magnitude of the acceleration of the blocks? (a)

5.0\,\text{m/s}^2

(b)

2.0\,\text{m/s}^2

(c)

1.7\,\text{m/s}^2

(d)

1.0\,\text{m/s}^2
