AI Generated Solution

To solve the problem step by step, we will first calculate the force of kinetic friction and then find the acceleration produced when a horizontal force is applied. ### Step 1: Calculate the Normal Force (N) The normal force (N) acting on the box is equal to the weight of the box since it is on a horizontal surface. The weight can be calculated using the formula: \[ N = mg \] Where: ...
