Question
The figure shows the forces exerted on a block that is sliding on a horizontal surface: the gravitational force of 40 N, the 40 N normal force exerted by the surface, and a frictional force exerted to the left. The coefficient of friction between the block and the surface is 0.20. The acceleration of the block is most nearly
  1. $1.0 \textrm{ m/s}^2$ to the right
  2. $1.0 \textrm{ m/s}^2$ to the left
  3. $2.0 \textrm{ m/s}^2$ to the right
  4. $2.0 \textrm{ m/s}^2$ to the left
