A brick is initially at rest on top of a rough horizontal surface, as shown in the diagram. The brick is pushed by a force F=25N parallel to the surface and starts to move. The weight of the brick 𝑊=28N.What must the coefficient of static friction of the brick with the surface be less than?

A brick is initially at rest on top of a rough horizontal surface, as shown in the diagram. The brick is pushed by a force F=22N parallel to the surface and starts to move. The coefficient of static friction of the brick with the surface is 0.75. What must the weight of the brick, be less than?
A brick is initially at rest on top of a rough horizontal surface, as shown in the diagram. The brick is pushed by a force F parallel to the surface. The weight of the brick W=30 N.
The coefficient of static friction of the brick with the surface is 0.75. What must the magnitude of F exceed to start the brick moving across the surface?

so, you've taken the time to post the same thing three times.
Have you actually done any work on it yet?
You only have a few numbers to work with, and clearly at this point, you have only learned a few formulas and rules for motion. So, any problem assigned will use one of those few rules. So review the topic and post your work on attempting to solve the problem. "I am clueless" just means you haven't bothered to study yet.
