Problem

2\,\text{kg}

block is in contact with a

3\,\text{kg}

block on a horizontal surface with negligible friction. A horizontal force of

25\,\text{N}

pushes on the

2\,\text{kg}

block so that both blocks move together. What is the magnitude of their acceleration? a)

12.5\;\text{m/s}^2

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

25\;\text{m/s}^2

2.5\;\text{m/s}^2
