Problem

Blocks E (

1.5\,\text{kg}

) and F (

2.0\,\text{kg}

) rest in contact on a horizontal surface. The coefficient of kinetic friction between each block and the surface is

0.20

. A horizontal force is applied to the right side of block F, causing the two-block system to move leftward with a constant acceleration of

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

. Take

g = 9.8\,\text{m/s}^2

. What is the magnitude of the applied force? a)

7.0\,\text{N}

3.5\,\text{N}

10.4\,\text{N}

13.9\,\text{N}
