The image is from an educational website, showing Part B of a physics problem.**Part B**- **Question:** What is the friction force on the upper crate under the conditions given in Part A?- **Instruction:** Express your answer in pounds.There is an input box for entering the value of the friction force, denoted as \( F \). Below the input area, there are options to submit the answer or request an answer. There is also a "Provide Feedback" link and navigation buttons, including "Next."This section is part of a sequence in a problem set, designed for educational purposes to help students practice calculations related to friction forces. At a construction site, a pallet of bricks is to be suspended by attaching a rope to it and connecting the other end to a couple of heavy crates on the roof of a building, as shown in the diagram. The rope pulls horizontally on the lower crate, and the coefficient of static friction between the lower crate and the roof is 0.399.**Diagram Explanation:**- The image shows a roof with two crates on top. One crate weighs 150 lb and is placed on a 250 lb crate.- A rope goes over a pulley attached to the roof's edge, connecting the lower crate to a pallet of bricks hanging off the side of the building.**Part A**What is the weight of the heaviest pallet of bricks that can be supported this way? (*Hint: Start by drawing appropriate free-body diagrams.*)Express your answer in pounds.

Part D Assuming that the angle at which you push on the edge of the box is again 45°, with what magnitude of force Fp should you push if the box were to slide down the wall at a constant velocity? Note that, in general, the magnitude of the friction force will change if you change the magnitude of the pushing force. Thus, for this part, assume that the magnitude of the friction force is f = 0.516Fp. ► View Available Hint(s) Fp= [ΨΕΙ ΑΣΦ = ? N
