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.
