can you please help me with this assignment, please show all the work.

This is Physics 20 (grade 11)- Module 3- Lesson 4 - Free Body Diagrams and Net Force

I have done question 3 B. I just want you to help me describe A:

Question 3 Consider now the following two scenarios: Answer saved Marked out of 5.00 Flag question mz Two blocks in contact are pushed Two blocks in contact are pushed at a steady speed to the right with a steady force to the right and on a rough surface. accelerating on a rough surface. A student creates the following free-body diagrams: Fret - x = Fr - FF normal Fnet - x = Fr - FF normal Fret = 0 Fret > O FFriction Fronsion Ffriction Fronsion gravity FgravityBOTH of these free-body diagrams are INCORRECT. a) Identify any errors the student has made in their Free-Body- Diagrams (1 mark) b) Create the CORRECT Free-Body-Diagrams for these two scenarios (4 marks)friction Fnormal A- Fnormal Fnormal mz F friction Fnormal Fgravity Fgravity FNet = O Fnormal 2 Fnormal Fnormal K - mz Ffriction Ffriction Fgravity Fgravity Fnet 7 0 HilroyQuestion 5 A truck is driving at a constant velocity up a steep slope (see image below). A toolbox is riding on Answer saved a trailer which is towed behind the truck as shown. Marked out of 5.00 Flag question a) Draw a Free-Body-Diagram for the TOOLBOX. Make sure you list ALL forces and draw the magnitude of the vectors appropriately. (2 marks) b) Suppose the driver slams on the brakes, abruptly stopping the truck. . Describe the motion of the toolbox once the driver presses the brakes. (1 mark) . EXPLAIN the motion of the toolbox using Newton's Laws of Motion. (2 marks)
