Question
The following question has multiple parts; please work them in the order shown.

**Part A)** What is the force of friction on the box which is staying at rest on the incline below?

*Diagram Description:*
- A brown incline at an angle of 23.4° with a yellow box on it.
- The box has a mass of 27.5 kg.

*Answer Section:*
Ff = [blank] unit[blank]  
Pick a direction from the options below:
- Green arrow pointing down
- Purple arrow pointing up
- Orange arrow pointing right
- Four red arrows pointing at different angles

**Part B)** What minimum value must the coefficient of static friction, between the block and the incline, have?

*Answer Section:*
μs = [blank]

**Part C)** What would the net force on the block be, if the coefficient was changed to 0.05?

*Answer Section:*
Fnet = [blank] unit[blank]  
Pick a direction from the options below:
- Green arrow pointing down
- Purple arrow pointing up
- Orange arrow pointing right
- Four red arrows pointing at different angles

**Part D)** What then would be the acceleration of the object?

*Answer Section:*
a = [blank] unit[blank]  
Pick a direction from the options below:
- Green arrow pointing down
- Purple arrow pointing up
- Orange arrow pointing right
- Four red arrows pointing at different angles
