Step 1
Since you have asked multiple questions, we will solve the first question for you. If you want a specific question to be solved then please specify the question number or post only that question.
The constant velocity implies zero acceleration.

Step 2
Let's write a net force equation in terms of frictional force Fk , the weight mg.
The net force equation for vertical motion.
N-mg=Fnet,yN-mg=0N=mg
The net force equation for horizontal motion.
F-Fk=Fnet,xF-Fk=maxF-Fk=m×(0)F=FkF=μkN=μk×(mg)=0.2×(25 kg×9.8 m/s2)F=49 N
Therefore, the force exerted on the box is 49N.
