You push with a horizontal force of 43.7N against a 25.0N box, pressing it against a rough wall to hold it in place. The coefficients of kinetic and static friction between this box and the wall are 0.300 and 0.600, respectively.

1- What is the friction force on the box?

2- How hard would you have to press for the box to slide downward with a uniform speed of 12.0cm/s?
